It was Eto'o who decided the game with a late strike.
“I don't think a player can change much in a team,” he told Sky Sport Italia.
“Inter are a great side of champions and when we play at the level we did tonight, we can win in any stadium.”
The Cameroon international played in a wider role for the 4-2-1-3 system, matched by Goran Pandev on the other flank.
“The Coach told me two days ago I would be playing in that position. It is a sacrifice for the team that I must make and we are all very happy.”
Wesley Sneijder's wonderful pass released Eto'o for the winning goal in London.
“Wesley is a very important player. He put two balls there for me. I made a bad decision on the first one, but with the second I just had to put it in the back of the net.”
