Arsenal go to Bayern Munich next with their Champions League Quarter-Final hanging in the balance. But, after their German opponents had turned around an early Bukayo Saka goal to lead 1-2, Arsenal managed to rescue the tie through Leandro Trossard. The reason? Mikel Arteta's brilliant in-game changes that allowed his side to dominate, then salvage, this huge game.
