Arsenal boss Arsene Wenger has been frustrated since his side Tuesday’s 2-0 defeat to Barcelona in the first leg of their last-16 Champions League clash.
Lionel Messi’s double has given holders a strong lead ahead of the return leg next month.
“It is too easy to blame, you have to respect the effort of the players, but it is very frustrating. Barcelona can always kill you when you think that you are on top. They are very quick and were better than us, there is no shame to say that. It will be very difficult in the second leg, but we have to try to give our best. It is 95% for them and 5% for us, but we will have a go and you never know,” Wenger revealed.
