Barcelona midfielder Andres Iniesta is unlikely to move to Manchester United despite reports suggest the Spanish international is unhappy with being rotated by manager Tato Martino.

Iniesta has started just eight of Barcelona's 13 La Liga matches this season with Martino keen to alternate amid the Catalans' gruelling domestic and European schedule.

The 29 year old is understood to be unsettled at the Nou Camp, particularly with discussions regarding a new contract, which expires in 2015, having stalled and report claimed that United would launch an ambitions bid to sign the midfielder.

But Mendieta, who spent a season on loan at Barcelona during the 2002/03 campaign, says any deal is very unlikely.

"You can never say never but I think Iniesta is happy there," Mendieta told talkSPORT. "I think the fact that he has not been playing regularly a she would like to, Tata Martino is employing this rotation which I think we agree they all need.

"I'm sure there will become a point where Iniesta and Barcelona reach an agreement. The both say there is no rush in the negotiations and both are happy to wait and see what happens."

After a summer transfer window which saw just one significant signing in Marouane Fellaini, United boss David Moyes is expected to venture into the market in January in search of a new central midfielder.

Moyes has claimed United are "five or six" world class players short of competing for major silverware and will make a creative presence a primary objective in the New Year.

Bids for Cesc Fabregas and Ander Herrera were rejected in the summer after Moyes joined United on 1 July, following new executive vice-chairman Ed Woodward.

Reports of a move for Iniesta appear particularly farfetched, not least with Barcelona sporting director Andoni Zubizarreta hopeful of him signing a new deal.

"Iniesta's case is progressing, progressing," he said. "These are big names in football, they do not renew from one day to the next. I am optimistic."
