The host of Premier League clubs chasing Athletic Bilbao winger Iker Muniain are in a race against time to agree a deal for him, reports the Daily Mail.
Munian, 21, has only got one-year left on his current deal but, thanks to a special clause in his contract, will see his release clause rise to a massive £40m on July 1.
It's a familiar clause to that of Ander Herrera, who almost joined Manchester United on transfer deadline day last year.
Manchester City, United, Arsenal and Liverpool have all tracked Muniain this season with his fine form for the Basque club attracting admiring glances from all over Europe.
With only 12 months left on his contract, the aforementioned clubs believed a bid of around £14m would be enough to convince Bilbao to sell, but, as always, the Bilbao board are proving difficult to deal with.
With the club's strict policy of only playing Basque players - with the exception of few - it means they rarely sell a player for under his release clause as money has less value for them because finding replacements is such a difficult process.
Clubs are now resigning themselves to the fact that Muniain won't be leaving Spain before his £40m contract clause is activated and are instead trying to convince the player not to sign a new deal.
Joining up with Arsenal to play under Arsene Wenger, who is renowned for developing young talent, could prove difficult to turn down. While at the Etihad Stadium, a growing Spanish contingent would welcome Muniain to Manchester City with open arms.
Manchester United would struggle to beat their rivals to such a player as they can not promise Champions League football next season or even a future at the pinnacle of football. Sacking David Moyes is a sign of uncertainty at Old Trafford.
