Birmingham are happy to sell defender Martin Taylor to West Brom for £1million - but only if they manage to sign Gary Cahill from Aston Villa.

Taylor is firmly out of favour under Alex McLeish at St Andrews after returning from a loan spell with Norwich.

And Baggies boss Tony Mowbray wants the 28-year-old to shore up his backline, which has shipped in 35 goals in 28 league games, according to The Mirror.

Blues are happy to let Taylor move to The Hawthorns, but only if his place in the squad is filled by Cahill, who spent a successful loan spell with Sheffield United but is now back at Villa Park.

McLeish has already had one bid rejected by Villa chief Martin O'Neill, who rates Cahill in the £4million bracket.

O'Neill is in no rush to sell his highly-rated centre-back and said: "A number of teams have not only enquired about Gary, but a number of clubs have put offers in - none of which have been acceptable to us or have been accepted by us.

"Birmingham City, I can confirm, have made an offer but I have not accepted any of the offers because they do not meet the valuation.

"I am not in a hurry to sell Gary but he doesn't want his career to remain stagnant and I can't guarantee him playing in our side immediately. But things can change."
