Gabriel Martinelli will “make a real difference” to Arsenal when he returns to full fitness, according to Kevin Campbell.

However, speaking exclusively to Football Insider correspondent Dylan Childs, the former Gunners and Everton striker insisted that he will not “put too much onus” on the 19-year-old after a long lay-off with injury.

Martinelli was spotted training in a video released prior to the trip to Leeds United on Sunday as he prepares to make his return from a knee injury suffered in June.

His 26 senior appearances for Arsenal have yielded 10 goals and four assists including a sensational solo goal against Chelsea last January.

Goals have been difficult to come by for Mikel Arteta’s side this season and Martinelli’s return could offer welcome competition for Alexandre Lacazette.

When asked by Football Insider if he was excited by the prospect of the teenager’s return, Campbell said:“One thing I will not do is put too much onus on the young man.

“He has had a serious injury and it has been a long-term injury. You have to give him a bit of time.

“He is a very exciting player. Do we expect him to hit the ground running straight away? No we do not but he can make a real difference when he is fully fit.

“He plays at a 100 miles-per-hour. He is a big talent.

“It will be great to have him back within the fold but I will not put too much pressure on him.”
