Manchester United boss Louis van Gaal insists Robin van Persie is in good form.
Van Gaal is adamant his compatriot will regain his confidence in front of goal, and claims the 31-year-old is still at the top of his game despite a drop in form.
"He has showed that at the World Cup and is showing that now, except for scoring goals. But that is only a matter of time," Van Gaal told The Sun.
"A striker also needs a bit of luck and then the confidence is higher.
"But he's self-confident, so I expect he shall score and maybe against Chelsea.
"Now he is more fit than ever and playing better but doesn't score as much.
"He's been a little bit unlucky, like against West Brom when he shot with his right foot - it was hard to believe that shot stayed out of the goal."
