Arsene Wenger spoke ahead of the UEFA Europa League round of 16 clash with Milan, stating that his team needs to solve a psychological problem.
The "Gunners" secured a 2-0 victory in Italy in the first leg, and will play the second leg at home, but maintaining concentration from the start will not be easy.
The capital footballers had already relaxed in the previous stage of the tournament, when they defeated "Ostersunds" away 3-0 but suffered a 2-1 loss at home in front of their own fans.
"Europe brought a psychological problem," said Wenger. "When you win away, you must finish the job at home, but it's not easy because the team playing against you is always in a position where they have nothing to lose."
Despite their poor performance in the last three weeks, Arsenal's manager hopes to receive as much support as possible at the Emirates Stadium tonight.
"I played in full stadiums for 22 years and I am grateful for that," added Wenger. "If there are one or two games where the stadium is not full, we must look at ourselves and win back the fans."
The Gunners' clash with Milan tonight will kick off at 22:05 Lithuanian time.
