Reported Liverpool target Juan Mata is appears likely to leave Valencia in the summer with interest in his signature seemingly growing by the day.
Having been forced to cash-in on David Villa and David Silva last summer, Los Che are reluctant to lose another of their star turns, but could be forced into a sale if the 23-year-old's release clause is met.
As previously reported by skysports.com, Liverpool are one of the clubs chasing the winger and now his father - who also acts as his agent - says interest in his son has reached 'fever pitch'.
"The race to sign my son has hit fever pitch and is still increasing," said Juan Mata Snr, according to tribalfootball.com.
"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."
Along with Liverpool, Manchester City are also said to be chasing the Spaniard, who could command a fee of around €23 million.
The acquisition of more potent wide options is known to be a transfer window priority for Liverpool, and they have reportedly already secured the signing of Rennes flyer Sylvain Marveaux.
However, Liverpool are expected to further enhance their attacking options and a busy summer at Anfield seemingly beckons.
