The Eagles' boss believes he can re-build the confidence of the Morocco international by showing him some love, backing the 29-year-old to prove his worth at Selhurst Park
The 29-year-old joined Arsenal from Bordeaux in 2010, but after scoring seven goals in 29 league appearances in his debut season, has featured just 23 times in all competitions since.

"It's about him getting going again and I normally do all right with people whose careers are faltering," Holloway told the Daily Mail after the 1-0 pre-season defeat against Lazio on Saturday.
"I love them and work with them. Hopefully I can get him back to what he played like when he first went to Arsenal.
"There was nothing wrong with him when he scored eight in nine. But I wouldn't fancy being Robin van Persie's understudy. It couldn't have been fun."
The deal, which looks likely to be finalised next week, will mark Holloway's seventh new addition of the close-season.
