Nahki Wells is still being tracked by a Premier league club, according to recent reports, with Aston Villa the bookies’ favourites to sign the striker who has netted 15 goals already this season.

Sunderland are another Premier League club said to be interested in Wells, but Bradford City insist they have received only one bid for the 23-year-old since the January transfer window opened.

It was an improvement on Peterborough’s bid last summer, which was turned down, but still below what the club are hoping to get for their top striker. They value him at more than £2?million.

Sky Bet Championship side Middlesbrough were yesterday also strongly linked with the former Dandy Town man. “One is still in the ring,” admitted Julian Rhodes, the Bradford chairman. “They’ve been on to Phil [Parkinson] about Nahki and on that basis they could be coming in with something. We get inquiries every day but we’ve had no formal offers other than the one last week.”

David Baldwin, director of operations at Bradford, anticipates other offers to come in for their top player. “There will possibly be other offers, but when they occur, the club will act accordingly on the information we receive,” Baldwin said.

“We can’t do more than that. But from a football perspective, Nahki continues to go out there and hopefully carry on scoring goals. Unless we see any other offers coming through, which we feel are worth considering, Nahki remains very much a Bradford City player and part of our plans.”

Baldwin insists there is no specific amount in mind but the club are wary that with 18 months of his contract left, Wells’s value will start to depreciate.

“When an offer comes in, it is discussed with the two chairmen and, as we stand, the first one is not something we want to accept,” he said of the recent offer. Contrary to message board comments, we aren’t going to put a specific price on his head. Football is very speculative as to values. We are not attaching a ‘for sale’ sign to the back of our player. That’s not what the club is about.”

Baldwin added: “Nahki Wells is obviously an integral part of this current team. That asset element disappears by each transfer window. In the summer window, you are in danger of having a lesser value because he has less time on his contract. Come January 2015, he is able to sign a pre-contract for nothing.”
