De Gea is in awe of RvP's finishing ability.
"You can only sit back and admire his finishing inside the penalty area," De Gea said of Van Persie in the Manchester Evening News.
"When the ball falls to Robin it's as if you can predict the outcome before he's even taken his shot - he's deadly inside the box and he knows where the goal is.
"I have to admit he scores a few goals in training against me. We all try to make it as hard as possible for him, but he still manages to score sometimes.
"On the pitch he has settled extremely quickly. Of course we knew he was a fantastic player when he was at Arsenal, but it's not always easy to transfer that form to another club. He's done it right from the start."
