The Blades, Middlesbrough and Derby have all shown firm interest in the Ipswich striker throughout the summer, with the Bramall Lane club having a bid of around £5million rejected earlier in the window.

While Middlesbrough’s sale of Patrick Bamford to Leeds is believed to have freed the Teessiders up to make their move, the Sheffield Star is reporting the Blades maintain an interest despite manager Chris Wilder ruling his side out of the bidding on two occasions.

Derby also need to move players on if they are to move for Waghorn, with the proposed sale of Matej Vydra to Leeds falling through in recent days.

It’s understood the Blues will not sanction Waghorn’s sale until they have a replacement in the building, with Accrington’s Kayden Jackson having been lined up.

Ipswich are one of a number of Championship clubs to have shown serious interest in Jackson, who Accrington value at £1.25m.

Work continues regarding defensive additions, with Curtis Tilt of Blackpool remaining a serious target.

We exclusively revealed yesterday that the 26-year-old has handed in a transfer request in a bid to force through a move, but there has been little progress since, with Blackpool standing firm in their valuation of the player. It’s understood owner Marcus Evans is losing patience regarding a continual moving of the goalposts in regard to a fee.

The Blues were originally quoted £1million for Tilt, who has a year remaining on his contract, with the Blues having two bids rejected up to the value of £600,000.

It’s understood that a move could still be made for Hurst’s trusted stalwart Toto Nsiala – a central defender he signed for both Grimsby and Shrewsbury.
