Roma manager Luciano Spalletti believes Mohammed Salah can regain form if he goes back to basics.
Salah stormed to six goals in 14 matches for Roma, but picked up an injury that sidelined him.
The Egypt international was out for four weeks, but Spalletti expects him to return to form.
“He’s been affected by his injury,” Spalletti said at a media conference. “He hasn’t rediscovered his brilliance and inspiration again.
“The first thing he has to do is beat his man, he has to think about beating his man, that’s his thing.
“He is good with the ball at his feet. We’re working on his positioning.”
New signing Stephan El Shaarawy could come in for Roma against Frosinone this weekend after completing his loan deal from AC Milan, although Spalletti remains unsure how much of the game he will be able to play.
He added: “We’ll have to figure out if he can make a contribution during the game, or if it’s better to have a look at him in a few more training sessions.
“He’s coming off a period where he hasn’t been playing during his previous loan spell at Monaco, so it’s more likely he’ll come on during the game.
“He has important attributes, he has good technique and knows where the goal is. We’ll find his role.
“He can be a third striker, but at the same time he knows how to play every role across the front-line.”
