Speaking to reporters ahead of the game, the German coach said, "I think with Bukayo Saka and Martin Odegaard they always attack on the right, at least the beginning of an attack. They try to create an overlap there to get through or to switch sides. We didnât learn anything new from the league game on Sunday [when Arsenal lost to Aston Villa].
"Itâs all very flexible, the transitions are very fluid. Most of the time everything happens, theyâre not a team that commits to one formation. You can recognise a lot of automatic, but also free-running moves."
He added: "We played very attentively in the first leg. They play a very attractive style. They play at the highest level. We did well in the first leg, but itâs only half-time. We need everything again and hope that the home game will be the deciding factor."
