Did you see it coming?
Alves had let his contract wind down, and admitted even a day earlier at the club's Champions League victory parade he could leave, and did not know what the future holds, quoted by The Mirror.
Andy Mitten, editor of fanzine United We Stand, used his Twitter page to cite Alves as simply using United's interest to land himself a better deal.
Any other big name footballer want to use MUFC as a bargaining chip?— Andy Mitten (@AndyMitten) June 9, 2015
He was not the only one to express the sentiment, but at the same time, Alves would not be the first player to use interest from Manchester United as leverage.
United's situation at right-back remains unclear, with Rafael da Silva falling out of favour under manager Louis van Gaal, who preferred to play winger Antonio Valencia in the position.
Nathaniel Clyne of Southampton is one alternative the Red Devils could consider, who The Mirror reported Liverpool made an attempt to sign just a fortnight ago. The England international has one year remaining on his contract.
Here is a look at how United fans reacted to Alves' decision to stay put at Barcelona...

Dani Alves,Aleix Vidal & Danilo are settled. Now i see Clyne as our only hope. #mufc— Real Yardie. (@MannuJr) June 9, 2015
So glad Alves has signed a new contract at Barca!! Didn't want him at OT #MUFC— RED ARMY (@REDARMY1878) June 9, 2015
People annoyed that Alves has resigned! If you're looking to build a team he wasn't the right player anyway. Seamus Coleman is though #mufc— Sean O Farrell (@sofarrsogud) June 9, 2015
