His team-mate Silva is also available and Manchester
United are sure to fancy the attacking midfielder, who may fetch up
to £20million.
The Spanish team want to raise £50m by selling both
players but Villa could cost £40m alone if a bidding war erupts
between the Premier League's richest clubs.
Insiders say Villa, who has fired 121 goals in 223
outings for Valencia and 37 in 55 internationals, will also be
wanted by Barcelona and Real Madrid. But he is thought to prefer a
move to the Premier League, with Chelsea his first choice.
Nicolas Anelka is stalling over an extended one-year
deal at Chelsea and Blues fans would view Villa, 28, as an
eye-popping replacement.
Villa said: "For now my head is in Valencia and the
World Cup. "After South Africa I will decide what's best. My final
decision won't be based solely on money."
