Down, but not out. As 1-0 defeats go this was the vaguely encouraging kind for Arsenal, who even in defeat will leave Germany with the knowledge that progress remains within their grasp. Lea Schüller’s towering header was the difference between the sides here, but over the 90 minutes Arsenal created enough chances to offer plenty of hope for the second leg at the Emirates Stadium.The burning question, of course, is whether Arsenal will manage to take any of them. Twenty-five shots came and went for them, seven of them to the luckless Stina Blackstenius. But Bayern really did need to be at their resilient best in a pulsating second half, as an injury-depleted Arsenal managed to exert some serious pressure against a team that has conceded just four league goals all season. Caitlin Foord was probably Arsenal’s most dangerous player, cutting in off the left flank and creating all kinds of problems.
