'We know that ( in the first leg ) we were impatient and threw ourselves forward too much , that we lost our patience and composure .

We just focussed on attacking well , but because a goal did n't go in we opened ourselves up . ' Wojciech Szczesny ( centre ) may have to settled for a place on the bench on Tuesday night .
