Moyes has been installed as Sir Alex Ferguson’s replacement at Old Trafford and is expected to try and bolster his newly-inherited squad when the window opens.
According to the Times, Manchester United are working hard and trying to get a deal for either one of the two Barcelona midfielders over the line.
A deal for Fabregas may prove too difficult as Arsenal have the first option on him following his move to the Nou Camp from north London in 2011.
Fabregas has also insisted this week he has no intention on calling time on his Barcelona career just yet.
Alcantara may represent a more realistic signing because of the €18 million release clause written into his contract.
The clause in Alcantara’s contract dropped to that figure because he didn’t play at least 60% of Barcelona’s matches last season. If he had made enough first team appearances, Manchester United would have had to pay an eye-watering €90 million to activate the clause instead.
The young Spaniard is currently away with his country’s U21 squad at the European Championships in Isreal.
