Fulham boss Chris Coleman believes teenage striker Collins John could be the next Premiership sensation.

The previously little-known Liberian came off the bench at the Walkers Stadium to fire a two-goal salvo, condemning the relegation-threatened Foxes to their second defeat of the week and securing the Cottagers’ first league win on the road since October.

John had been signed from Dutch outfit FC Twente Enschede in January for a fee Coleman declined to disclose but described as “a good fee for an 18-year-old”.

“There were one or two big clubs after him but luck was on our side and we were the ones who managed to sign him,” Coleman said.

“He’s played for Holland at Under-18 level and at Under-21 level.

“He’s a strong boy, big for his age, and he could certainly be a big player for us if he keeps banging them in like that.

“But at the moment he’s one for the future and we’ll be feeding him in and out of games.

“During the game we were defending for our lives at times but we knew Leicester would put us under pressure.

“In fact prior to our first goal we were under pressure so I was really pleased with the way Collins went about his business.

“We’ve had some adverse publicity recently for supposedly being negative away from home but I don’t care about that because we’ve got three points.”
