Arsenal have been encouraged in their pursuit of Spanish international Juan Mata after Valencia revealed the forward could leave the Mestalla this summer.

Coach Unai Emery acknowledged the club wouldn't prevent Mata from leaving Spain should a big enough offer arrive.

The 23-year-old has already won 11 caps for the senior Spain side and led the Under-21s to the European Championship title in June. Earlier this month, the player claimed he is happy at Valencia and focused on winning trophies next season. But Emery admits the club are powerless to stop the player leaving if a large enough bid comes in.

"Valencia has to be prepared for a footballer having to leave, either because he is not wanted or because some big club wants to sign him," Emery told Cadena Copa.

"We want him to stay and Mata has also expressed his wish to remain at Valencia, but we know that if a big-money offer comes in from any club and it's good for both the player and the club, it could lead to his exit."

Arsene Wenger views Mata is seen as an ideal replacement for Cesc Fabregas at the Emirates, but the Arsenal captain's protracted transfer to Barcelona remains unresolved.

Spain forward Pedro has become the latest in a long line of Barca players to openly discuss the Fabregas deal.

"We are all looking forward to see if he joins the club, we get on well together with the national team," Pedro said.

"He would adapt quickly as he has great quality. We know he is in a difficult situation, but hopefully the issue will be finished soon."

Fabregas was today granted his wish of being excluded from the club's pre-season training camp in Germany. The same hamstring injury that prevented him from travelling to Asia earlier this month continues to be a problem for the 24-year-old.

But Barcelona are yet to submit an improved £35m bid for the Spain international, despite Wenger's warning that they will not sanction a transfer after the end of the month.

The Arsenal manager has failed to convince Fabregas and Manchester City-target Samir Nasri that the club are prepared to meet their ambitions in the transfer market. The £11m purchase of Gervinho remains Wenger's only major signing of the summer, with the Arsenal board rumoured to have grown impatient with the Frenchman's reticence to pursue a marquee signing.

Yesterday, the club had a £10m offer for Everton defender Phil Jagielka rejected, with the bid nowhere near the Merseyside club's £20m valuation of the England international.
