Speculation suggested the two clubs had begun talks over a possible £15million deal for the winger, but with the Reds apparently only willing to pay half that figure.

Roberto Martinez: "We're not here to try to find business, we don't need to sell players to balance our books, and that's always our position.
"We're not talking to any clubs, so it's not as if there are negotiations that you hope break down."
