The Gambian teenager arrived on trial a fortnight ago in a bid to break into the Premier League.

He caught the eye when he marked his Blues debut against Exeter by winning the penalty which secured the visitors a 1-1 draw.

Krumah followed that up with two assists in his 45 minutes at Swindon last Friday and also turned out against Dorchester earlier in the week.

Now Redknapp has confirmed the pacy striker will be rewarded for his superb start with a Pompey deal.

Yet, while Blues boss believes it is too early to blood him into the Premier League he has high hopes for the future.

He said: 'OJ has done well, he's only 18 and I think he's a real prospect.

'We're hoping to now get something done and keep him here permanently because I like him.

'He was at Southampton last year, they wanted him but could not get a work permit but he's married now so that's no longer a problem.

'The lad was recommended to me so we had him over for the last couple of weeks and he's been tremendous.

'He's quick and has got a lot of everything.

'The kid wants to do well, he's willing to learn and hopefully he can do well here.

'I have already had half a dozen clubs wanting to play him this season, most of them are from the Championship.

'He's not ready for the Premier League but he's still young so his time can come.'
