Xavi reportedly rejected the chance to become Manchester United's new manager when Ole Gunnar Solskjaer was still in charge of the 20-time English champions.
Solskjaer was sacked by the Red Devils last November, with Ralf Rangnick taking charge of the team on an interim basis for the remainder of the 2021-22 campaign.
Paris Saint-Germain's Mauricio Pochettino and Ajax's Erik ten Hag are believed to be the favourites to become Man United's permanent manager ahead of next season.
However, according to El Nacional, the Premier League giants had been interested in Xavi when the Spaniard was still in charge of Al-Sadd.
The report claims that Man United had sounded out the legendary midfielder to determine whether he would be interested in taking charge of the club.
However, Xavi made it clear that he was waiting for Barcelona, with the 42-year-old eventually taking charge of his former club last November.
Xavi has won 12, drawn seven and lost four of his 23 matches at the helm, with the Catalan giants now fourth in the La Liga table and chasing success in the Europa League.
