David de Gea is determined to focus on the European Under-21 Championship before deciding whether to join Manchester United.
The Premier League champions have identified the Atletico Madrid goalkeeper as Edwin van der Sar's successor and have confirmed they are deep in negotiations with his club.
On Tuesday some Spanish papers reported that United have agreed to pay Atletico a fee of €21million (£18.8m) to secure De Gea's services.
But while the 20-year-old keeper has admitted he wants to play at the highest level, he insists he will not discuss his future with the media until after the Under-21 tournament in Denmark.
De Gea, who has made eight appearances for the U21's and is yet to win a full cap, is currently preparing for Sunday's opener against England.
And speaking from Spain's training camp, he said: "I will only speak about my future after the end of the Euro Under-21s.
"Right now my challenge is to help the Spain team, but generally my desire is to play at the top and to improve day to day."
At the end of last month, De Gea's lawyer denied that the promising keeper has already agreed to join United and said he would not consider any offers until the end of June.
De Gea helped Spain's U17 team win the 2007 European Championship and finish second at the 2007 World Cup.
He made his Atletico debut in September 2009 aged 18 and has already racked up 84 first-team games for the Spanish side, who finished seventh last season.
