Mikel Arteta said Arsenal "lacked that magic moment" after losing to Bayern Munich and missing out on a first Champions League semi-final since 2009. Joshua Kimmich’s second-half goal was enough to secure a 3-2 aggregate win. "I thought we had the capacity and the quality to win the semi-finals because the margins have been very small," Arteta said. "But those margins are coming from something else that maybe we don"t have yet and we have to learn it." ‘Small margins’: Arteta says Arsenal have plenty to learn after Bayern defeat Arsenal knocked out by Bayern after Kimmich header secures last-four spot Hardened Bayern show true colours and hand Arteta biggest challenge
