Having held a long-standing interest in Barcelona star and former Arsenal captain Cesc Fabregas, to the extent that a transfer record bid was rumoured to have been made last summer, there are once again strong reports that United are in pursuit of the Spaniard.
In his presentation as Barca boss, Luis Enrique was queried on the future of his midfielder and acknowledged the fact Fabregas was being pursued by Manchester United, with the Barcelona legend hesitant to dismiss a move.
"In principle, we have not taken any decisions like that because we still have time," Enrique told the media.
"Some players are now focused on the World Cup finals, which is their job, and how it should be.
"We need to assess and evaluate now and when the time is right we will go into that and we will talk about everything."
It is possible Arsenal may now step in to proceedings given Barcelona's inability to confirm that Fabregas remained a vital part of their plans.
Many expected Fabregas to take over from Xavi once the Barca veteran retired, but that may not be the case, despite the 34-year-old's future also being uncertain. Enrique's comments seemed to indicate the ex Gunner was someone very much worth trying for, and was not one of those he wished to keep at the club whatever it takes.
Rumours of a first refusal option for Arsenal may tempt the Gunners to take the Spaniard back to North London, though his return would likely impact the progression of the likes of Jack Wilshere and Aaron Ramsey.
Fabregas scored 13 goals in 55 games for the Catalan outfit this season, the most appearances he has made in a season since he returned to his boyhood club in 2011.
