Arsenal fullback Mathieu Debuchy is full of praise for AS Monaco.

Monaco dumped Arsenal out of the Champions League last month to setup a quarterfinal against Juventus, with the first-leg to be played this week.

Debuchy commented: "For us, they were very good defensively.

"It was less the case with them, but I think this is the area in which they are most effective.

"Juve should not underestimate them."
