Former Liverpool stalwart Pepe Reina claims David de Gea should be happy enough representing Manchester United as speculation regarding his fellow Spaniard's future continues to circulate ahead of the summer transfer window.

De Gea has been in superb form throughout the 2014/15 season to date, boosting his club's Champions League qualification hopes with a series of fine performances that are believed to have attracted significant attention from Real Madrid.

Rumours of a complicated relationship with Manchester United manager Louis van Gaal, since denied by the player, only served to fuel speculation that former Atletico goalkeeper De Gea could seek a big-money transfer back to La Liga and recent reports suggest that Real may have already set the wheels in motion with regards to the potential exit of current number one Iker Casillas.

De Gea is yet to agree an extension to his current Old Trafford contract which is due to expire at the end of next season, yet Reina believes that the 24-year-old should be content with his current role as Manchester United aim to return to European football's elite club competition following a one-year absence.

"He is one of the top 'keepers in Europe and this year he has been superb," Bayern Munich's Reina, who spent nine years with Liverpool between 2005-14, told Talksport.

"Maybe Real Madrid are looking for a 'keeper and De Gea is one of the names suggested, but I think he should be happy enough to play for Man United."

De Gea was named in the senior Spain squad for upcoming matches against Ukraine and the Netherlands, although he is likely to start on the bench against the former as Casillas remains first-choice for competitive fixtures.

Vicente del Bosque's side sit second in Euro 2016 qualification group C, three points adrift of Slovakia following a surprise defeat in Zilina back in October.

Spain will be without the services of strikers Paco Alcacer and Diego Costa for the visit of Ukraine, with Malaga's Juanmi having been called into the squad for the first time to cover a potential shortfall in the final third.
