Nahki Wells looks set to earn a new improved contract with Bradford City keen to tie the striker down in a bid to ward off interest from bigger clubs.The 21-year-old currently has another season to go at Valley Parade after the League Two side took up an option to extend his initial one-year deal.It's understood Reading and Charlton Athletic have sent scouts to watch the Bermuda international this season, and with Wells' stock rising even further after his hat-trick at Northampton, City look set to offer him a lengthier contract.Joint-chairman Julian Rhodes said they would be sitting down with Wells, one of the lowest paid players at the club, at the end of the season.“We exercised the option early to show how much we valued him and now we'll look to sit down and do something. He's a player we're very excited about,” he told the Bradford & District Advertiser.“He's a player we are very excited about. Speak to anyone in the boardroom and they'll tell you I'm probably Nahki's biggest fan.“He has been very impressive this season. For a player with his speed, he's got two good feet and is willing to take men on.“You also notice he's a brave lad and wins a lot in the air. He's got a bit of everything.”Rhodes is convinced he can play at a higher level having watched him develop as one of City's most dangerous players this term.“Nahki got the spectacular FA Cup goal against Rochdale but he really announced himself in the league in those two home games at Christmas. He ran Shrewsbury ragged in particular and formed a great partnership with James Hanson,” said Rhodes.“I think we are a different team when we play Nahki and Kyel Reid at the same time. They can both cause defences all kinds of problems because of their speed.“I'm sure Nahki can go on and play at a higher level.“Certainly if he keeps working hard and gets a good pre-season in him, he could be a big player for us next year.“Let's hope 12 months from now we are talking about him as the top scorer in League Two.”Wells, who is City's top scorer with 11 goals this season, was recommended to City by the club's former winger Mark Ellis.He joined Carlisle, managed by Ellis's former Valley Parade team-mate Greg Abbott, before Peter Jackson signed him after he impressed during a trial last summer.
