Adebayor and Vidic will clash at Old Trafford tomorrow as Arsenal face Manchester United in the first leg of the Champions League semi-final.
Adebayor said: “Vidic is the toughest I have played against.
“He is very good and knows how to handle strikers.
“He is ready to give his life for Manchester United and is very, very strong.
“He is absolutely top-class because he saves a lot of goals but also scores a lot.”
