MATT Mills looks set to become a Wanderers player this summer even if Zat Knight commits his future to the club.

The Leicester City defender has indicated he wants to quit the King Power Stadium but was expected to be a fall-back option if Knight turned down the deal currently on the table for him.

Wanderers are still waiting for a firm answer from the 32-year-old but it is rumoured within the club that the big centre half is willing to stay on for another season.

Even so, the gears are in motion to sign Mills and a firm offer is expected to be made before the end of the week.

Reports in Scotland claim Celtic have been told to stump up £3million to sign the one-time Manchester City man, but the Whites are confident of landing him for a fraction of that cost.

It is understood their opening gambit will be £1.5million – less than a third of the fee paid by Leicester to Reading 12 months ago.

Mills is keen to leave after falling out with manager Nigel Pearson last season and did not play a game in the Championship after February.

Celtic have already seen a part-exchange offer turned down for the 25-year-old and have also enquired about a season-long loan.
