Foles threw for three touchdowns - including two to Cooper - in a 27-13 win for his side just a week after tying the NFL record of seven touchdown passes in a single game.
Foles also made it 16 touchdown passes without an interception, equalling the record jointly held by Peyton Manning and Milt Plum, and Cooper was full of praise for the man who came in for the injured Michael Vick.
"He has great poise. He's going to sit in the pocket and kind of dissect the defence," Cooper told reporters.
The defeat was the Packers' worst home defeat since 2006 and the first time that they had lost back-to-back home matches since 2008.
