Defending champions Glasgow are aiming to become only the second side ever to retain the PRO12 title and are appearing in the play-offs for a fifth successive season.Connacht are moving into uncharted territory having never reached this point in the competition before. Pat Lams side have the confidence of a recent 14-7 victory over their opponents but know that knockout rugby is a whole different ball game. Ahead of this highly anticipated match we look at some of the key battles that could decide this semi-final.John Muldoon v Josh Strauss Connacht captain John Muldoon will play his 274th game for the province this weekend Both No 8s will be key to their sides attempts to build momentum. Strauss has grown over the course of the PRO12 season, he never takes a backward step and almost always breaks the gain line.The ever-present Muldoon provides Connacht with momentum and leadership. Connacht are in new territory, they must embrace the challenge ahead of them and it will be up to their captain to lead the way.Both Muldoon and Strauss should be quick to introduce themselves to their opponents fly-halves, set their stall out early with gain line breaks and provide the benchmark when it comes to work rate.Ultan Dillane v Leone Nakarawa Leone Nakarawa is aiming for the perfect final season at Glasgow Warriors Dillane and Nakarawa will look to disrupt their opponents set-piece and this both should add plenty around the park.Its Dillanes athleticism and physicality make him standout and hes one of a number of players that Joe Schmidt will be keeping a close eye on this weekend.Nakarawa does things on a rugby field that others can only dream of and makes it all look effortless. So far the Fijian has made 48 offloads, 14 more than any other player, and provides solid set piece proficiency alongside his attacking spark.Nakarawa has magic in his locker than few in world rugby can unlock so Connachts 22-year-old will need to play to his own strengths and step up on the semi-final stage.Bundee Aki v Peter Horne Connachts Bundee Aki will be looking to add to the 6 tries hes scored so far this season Both centre pairings will be instrumental in this Guinness PRO12 semi-final in order to ignite their respective back lines and ensure that opportunities are created and taken.Aki has been at the very heart of Connachts rise and has beaten more defenders (83) and made more carries (251) than any other player in the competition. Its his ability to read the game, his flair and his distribution that drives the province.Peter Horne will be making his 100th appearance for the Warriors and needs to be ready to use every ounce of that experience. In attack Horne will need to fire and then defensively he needs to be as robust as can be to limit Akis impact on the game.

Sidney Crosby raises his game another to level when the calendar reads November. The Buffalo Sabres know how dangerous he can be regardless of what month it is.Crosby looks to continue his high-scoring ways and help the Pittsburgh Penguins extend some lengthy winning streaks over the Sabres when the teams face off on Saturday night in western New York.The accomplishments by Sid the Kid are well-documented-- two-time Hart Trophy winner as league MVP, two-time Art Ross Trophy winner as league scoring leader, and a two-time Stanley Cup winner among many others.Over the course of 11-plus NHL seasons, November has clearly been Crosbys time to shine even brighter. His power-play goal in Friday nights 3-2 overtime win against the New York Islanders was the 73rd of his career, far and away the most hes had in any month.Crosby also assisted on Kris Letangs game-winner 1:24 into the extra session.When hes got time and space, hes going to hurt you, Letang said of Crosby, whose career numbers against Buffalo are eye-popping.In 31 games, Crosby has 14 goals and 35 assists, helping the Penguins to a 22-7-2 record. In 17 career games at KeyBank Arena, Crosby has nine goals and 19 assists leading them to a 12-4-1 mark.Pittsburgh (11-4-2) has won nine straight from the Sabres by a combined 37-13 score, thanks in large part to 15 assists from Crosby, and six in a row in Buffalo by a combined 26-11 count with Crosby contributing 12 assists.Crosby has 11 goals in 11 games after missing the first six with a concussion, and is one goal shy of 350 for his career. Despite the delayed start to his season, Crosby is tied for second in goals, one behind rookie Patrik Laine of the Winnipeg Jets for the NHL lead.After Matt Murray defeated the Islanders, Marc-Andre Fleury may get the chance to bounce back from some recent subpar play. In his last three appearances, including two starts, Fleury has surrendered 11 goals in just over 162 minutes for a 4.06 goals-against average.But Fleury has hardly struggled versus the Sabres. In 26 career starts, Fleury is 19-5-2 with 2.18 goals-against average and four shutouts, and hes won seven straight starts in Buffalo, posting a 1.43 GAA and .950 save percentage with two shutouts.Buffalo (5-8-4) has not made the playoffs since 2011 and any hopes of ending that streak appear to be a long shot.dddddddddddd The Sabres are 1-4-2 at home, have an NHL-low 31 goals and are at the bottom of the Atlantic Division with 14 points.Left winger Matt Moulson said Buffalo needs to refocus on the ice.We talked (Friday) about concentrating on playing the right way, Moulson told the teams official website. It seems like were giving up a lot of odd-man rushes to some pretty skilled groups the last couple of games, so I think thats the focus. Playing the right way will lead to offensive chances and scoring chances.A three-time 30-goal scorer, Moulson has six goals in 17 games after totaling eight in 81 games with Buffalo last season. He also has two goals and an assist in a three-game point streak versus the Penguins.Among the Sabres struggling to score consistently is right wing Kyle Okposo. Though hes second on the team behind Moulson with five goals and has a team-best 10 points, Okposo has failed to score in six straight games, and he has just one goal at home.Weve got to make sure were playing the right way and we cant press, Okposo told the teams website.While with the Islanders, Okposo had a career-best four goals in a win over Pittsburgh on Jan. 16, 2015. In five matchups since then, hes had a goal and two assists.Buffalo center Ryan OReilly -- the teams second-leading scorer with nine points (four goals, five assists) -- is expected to miss his fourth straight game with an oblique injury.However, one player who could help the Sabres sputtering offense is left wing Evander Kane, whos been limited to six games this season after missing 11 with cracked ribs. Though Kane has just one assist so far, hes scored three goals and added six assists in his last five games against the Penguins.Defenseman Dmitry Kulikov (no points, minus-4 in 12 games) has missed the last four games with a back injury and is not likely to suit up Saturday for Buffalo.Right winger Patric Hornqvist (five goals, eight assists, 16 games) missed Fridays contest for Pittsburgh with a concussion suffered in Wednesdays 7-1 loss to the Washington Capitals. Its not immediately known if he will be cleared to face the Sabres. ' ' '
