United on alert as Barca prepare to sell £28m Alves after Champions League exit

Dani Alves will be the first high-profile casualty as Barcelona look to rebuild their squad this summer.



Pep Guardiola's side look set to lose their European and domestic titles, both possibly to arch rivals Real Madrid - failures which will force the Spaniard into the transfer market.



Guardiola has grown tired of Brazilian Alves' lack of defensive discipline and has been frustrated by him consistently this season, particularly during Saturday's 2-1 home defeat by Real, which all but handed the league title back to Madrid.



Exit ahead: Dani Alves could be one of the big name casualties at the Nou Camp this summer

Guardiola dropped the 28-year-old to the bench for the Champions League semi-final second leg against Chelsea and he was also completely left out of the squad for the Copa Del Rey semi-final against Valencia in February.



The defender also fell out with his manager after Guardiola stopped him from making a publicity appearance for one of his sponsors earlier in the season.



Alves has a contract at the Nou Camp until 2015, meaning Barcelona feel they can attract around 35million euros (£28m) for the right-back.



Wanted: Barca are keen to sign Tottenham winger Gareth Bale

But while some of the Barcelona hierarchy feel Manchester United could be persuaded to part with that kind of money, Russian moneybags Anzhi Makhachkala seem a more likely destination.



Sir Alex Ferguson, although open to the idea of a new right back, would be unlikely to spend so much on a player nearing his thirties.



Forward Pedro is another player under threat as Guardiola - if he stays - looks to raise money for moves for Tottenham's Gareth Bale, Valencia winger Jordi Alba and - less likely - Arsenal captain Robin van Persie.
