Manchester United reportedly targeting Dani Alves has once again fuelled speculations over his summer move away from Barcelona, while his agent, Dinorah Santana, has confirmed having already received offers for the right-back.

Being out of contract at the Camp Nou this summer, the Brazilian international is already free to negotiate a summer move to another club.

Even though the La Liga giants paid £23.5m to Sevilla in summer 2008 to secure his services they look now ready to let him go for free at the end of the campaign as they have yet to offer him a renewal deal.

Liverpool and especially Manchester United are said to be monitoring the situation, while Spanish newspaper Sport recently reported his agent was expected to fly to Manchester this month to discuss a move to Old Trafford after receiving Louis van Gaal's approach.

Alves has now sent an enigmatic message through his Instagram account that appears to be a farewell to his current club.

"Brazilian family, my pride, to be a part of this quintet makes me happy. If I have to leave, I do so with bravely, with a beautiful smile and happiness in my heart. No matter what happens; I tried to be happy, not perfect," Alves said in a photo with his Brazilian compatriots; Adriano, Rafinha, Douglas and Neymar.

Meanwhile, his agent Santana told to Spanish radio station Cadena Cope that she has already received some offers from other club while confirmed Barcelona are yet to propose him an extension.

"We have received some offers. Dani is listening to offers. We're speaking with teams and gathering information," she said.

Earlier this season the 31-year-old right-back revealed his intention to move to the Premier League. When asked whether the offers received come from English clubs, Santana responded: "All the offers have come from non-Spanish clubs. We haven't decided anything yet. We have to wait a little because we are not in a hurry, we will be patient to see what happens."

Meanwhile, asked whether Alves feels disappointed by Barcelona's apparent decision to let him go, she said: "We're more sad than disappointed with Barca, the club hasn't approached us at all, while we've been waiting for their call."

Meanwhile, on Thursday, Alves's teammate Adriano Correia urged the club's officials to rethink their plans and offer him a new deal.

"Dani wants to stay here and if I would have to renew him I will do it because our friendship and due to the respect for him as a footballer and his performances," Adriano said.
