Petr Cech 1 Arsenal face Chelsea in the Community Shield on Sunday, which you can hear live on talkSPORT, looking to retain the crown they acquired at this stage last season.The traditional curtain raiser for the new Premier League season has extra spice this time round, particularly after Petr Cech’s move to the Gunners and Jose Mourinho accusing Arsene Wenger of attempting to buy the title.Arsenal will be hoping they can replicate their impressive 3-0 win over Manchester City from the corresponding fixture last season as they look to mount their first genuine title challenge for over a decade.COMMUNITY SHIELD 2015: WHAT IMPACT DOES WINNING THE TROPHY HAVE ON THE DESTINY OF THE PREMIER LEAGUE TITLE?Wenger’s side have no new casualties, with Danny Welbeck still sidelined and Alexis Sanchez and David Ospina still on extended leave after the Copa America.Here is a possible Arsenal XI against Chelsea in the Community Shield:Goalkeeper:Even if Ospina was available for selection, there would have been very little debate as to who Arsenal would have between the sticks. After his controversial move across London last month, Cech will make his competitive debut against the side he served so imperiously for a decade. It remains to be seen what difference the Czech international will make in the Gunners’ title tilt this season.Defence:As you were. Despite Mathieu Debuchy’s return to full fitness, Hector Bellerin’s form at the back end of last season should see him retain his place. The strength in depth in that position raises questions about Calum Chambers’ future, although the former Southampton man can also play in the middle. Laurent Koscielny and Per Mertesacker formed an understanding last term, while Nacho Monreal came into his own in the left back role to keep Kieran Gibbs out of the side.Midfield:Francis Coquelin’s emergence was one of the stories of last season, and he may have saved Arsenal from having to dip into the transfer market for a defensive midfielder. Moving Santi Cazorla into a deeper role was also a stroke of genius, which should allow Mesut Ozil to thrive in the no.10 role. Aaron Ramsey should continue a hybrid right-sided role, while the absence of Sanchez may hand Alex Oxlade-Chamberlain a chance to shine.Attack:The most contentious position, particularly when you pit Olivier Giroud’s form from last season with the fact Theo Walcott has just signed a new long-term deal at the club. The Englishman’s display in the FA Cup final may just give him the edge, and he should feature upfront rather than out wide after Wenger intimated that’s where his future lies. Either way, it’s hard on Giroud.The Community Shield between Arsenal and Chelsea is live on talkSPORT from 3pm on Sunday.
