Wells has plundered 14 goals in all competitions this season and is one of the hottest properties around in the lower leagues.
League One rivals Peterborough had a bid rejected for the 23-year-old in the summer, but there are thought to be plenty of Championship clubs now interested in the former Carlisle man with QPR reportedly at the head of the list of admirers.
But despite all the reported interest, Bantams defender Davies is desperate for £3million-rated Wells to stay put for the time being and believes he is a far better striker than Crystal Palace forward Gayle, who signed from Peterborough for a fee of around £6million in the summer.
In his Telegraph & Argus column, Davies said: "I don't think he needs to go anywhere now. The fans love him, the gaffer loves him and the lads really like him.
"Nahki is only 23 and his big moves and his money will come. Keep scoring goals and it doesn't matter what team or division he's at, clubs will be interested.
"You look at Dwight Gayle, who went from Dagenham to Crystal Palace for £6million rising to £8million. I've played against them both and I don't think he can lace Nahki's boots."
