William Gallas says it's all about belief as we prepare for one of the biggest European nights in the club's history.
The team will first step out at the San Siro for training tonight (Tuesday) and then for the real deal against Italian giants, treble-winners and Champions League holders Inter Milan for our third match in the group stages of Europe's elite competition tomorrow night.
It will be right up there with European ties against Spanish giants Real Madrid and Barcelona in the 1980s and the last time we visited the San Siro for a famous UEFA Cup semi-final second leg in 1972, when Alan Mullery's goal secured a draw and a place in the final.
It's certainly a case of so far, so good in the Champions League with a draw in Werder Bremen and 4-1 win against FC Twente.
Vastly experienced in the Champions League, defender William insists we have to continue taking the tournament in our stride and be ourselves on the big stage.
"Everyone at the club is happy to be in the Champions League and to compete with the biggest teams across Europe," he said.
"Wednesday is a massive game for us. What we have to do is go to Milan and believe in ourselves and then maybe we can do something.
"It's true they won the Champions League last season but that doesn't matter now.
"We have to believe, to go there and see what we can do.
"We have to go and play and see if we can come back with one or maybe three points and if we manage to do that, it would be fantastic."
