Thiago Alcantara has been advised to join Manchester United this summer and could be joined in the Premier League by his younger brother Rafinha, reports suggest.

The Barcelona midfielder is currently weighing up his options between prolonging his stay at the Nou Camp or seeking a move where he would be assured of greater first team opportunities with United prepared to activate his €18m release clause.

The Daily Mirror report that the 22-year-old has been instructed by his World Cup-winning father Mazinho to give United's offer serious consideration, while also suggesting Thiago's brother and Barca teammate Rafinha could be subject to a loan offer from Everton in a move that could see the entire family relocate to the north west.

Should Rafinha, who operates as a forward for Barcelona's B ranks, not be tempted to join Roberto Martinez's side, the Mirror also suggest David Moyes will attempt to secure the signature of both the Alcantara brothers.

But both United and Everton could face competition from Celta Vigo, who are looking to secure 20-year-old Rafinha on a loan deal after their forward Iago Aspas completed his move to Liverpool.

The promising forward will be out of contract with the Catalan giants next summer, but Spanish newspaper El Mundo Deportivo suggest Tito Vilanova's side are set to offer him a two year contract extension before allowing him to leave the club on a temporary basis in a bid to secure greater first team football opportunities.

But United could be ready to rival those efforts and bring both of the brothers to Manchester.

With Xavi, Andres Iniesta, Cesc Fabregas and Sergio Busquets also vying for starling roles in Barca's midfield, head coach Vilanova has been unable to promise Thiago more first team opportunities than he was given last season.

The La Liga champions are still attempting to secure the future of the highly regarded 22-year-old with an offer of a new contract.

Barca stars Xavi and former United defender Gerard Pique have also urged the Spain Under-21 captain to be patient and remain at the Nou Camp, but Thiago's desire to secure himself consistent first team football may very well play the pivotal role in his decision.
