Arsenal emerged victorious from their Champions League encounter with Bayern Munich last night but it might well have come at a price. Speaking after the match, Arsene Wenger revealed how star man Alexis Sanchez is exhausted and hinted at the fact that he might now rest the Chilean in order to get him back to his best. Next up for the Gunners is Everton at home - not really the ideal match to have Sanchez missing - but Wenger is running the risk of the 26-year-old picking up an injury if he continues to play him. Meanwhile, Bayern Munich boss Pep Guardiola has promised Arsenal fans they will get good prices for tickets in their next European outing to the Allianz Arena. Bayern fans staged a protest at how expensive seats were at the Emirates Stadium, but Guardiola promised there would be no repeat in Bavaria.
