Wolves have upped the price tag on want away striker Kevin Doyle, potentially endangering a transfer to Celtic.

The Wexford man has been linked with the Hoops in recent weeks and according to The Sun, Celtic have been told by the League One side that he will cost at least €2.2 million.

Doyle had a poor season at club level, scoring just nine times in 42 games for the relegated Midlanders.
