The father of Juan Mata admits a move to England could be on for the Valencia star.
Chelsea and Manchester City have been in contact with Los Che for the midfielder, while Liverpool are also being linked.
Juan Sr, a former striker who now acts as his son's agent, said: "The race to sign my son has hit fever pitch and is still increasing.
"I still get calls from many agents in England but we are calm. If we get an offer in writing then we will take it to Valencia and let them decide."
