Rashford is a Manchester United player. He has a contract that runs to 30 June 2028. When Casemiro's contract expires on 30 June this year, he will be the club's highest earner, with his salary benefiting from the restoration of the 25% that had been taken off because of last season's failure to qualify for the Champions League.

His loan deal with Barcelona includes an option to make the transfer permanent for €30m (£25.94m) if it is triggered by 15 June.

That is the easy bit. From there it starts to get complicated.

On the face of it, making the deal permanent makes sense for all parties.

Rashford has done pretty well; 14 goals and 14 assists in 47 appearances. It was enough to earn him an England recall from Thomas Tuchel and, in all probability, a spot in the final 26-man World Cup squad.

He enjoys playing for Barcelona and would like to stay.

While Barca have other targets this summer, they would be signing a player for well under market value. Manchester United meanwhile would be washing their hands of someone who was in Ruben Amorim's 'bomb squad' last summer.

However, Barcelona are apparently unwilling to execute the transfer and are trying to renegotiate, potentially to sign Rashford next season on another loan deal. United have indicated they are not prepared to do that.

It is an understandable position for United, who know they could get more for Rashford from other clubs.

Yet United's stance has risk.

Last month, head coach Michael Carrick said 'nothing has been decided' on Rashford and indicated he would be willing to work with the 28-year-old if he returned to Old Trafford next season and he was confirmed as the new boss.

However, United are determined to drive wage costs down and minority owner Sir Jim Ratcliffe has previously spoken about trying to ensure the highest earners are 'on the pitch'.

Given the club are approaching a summer in which they will be attempting to sign at least two central midfield players and almost certainly at least two more players in other areas of the pitch, and also need to talk to skipper Bruno Fernandes about his contractual situation, it does not help them in negotiating terms for someone on Rashford's salary to still be at the club.

It's been rare for Rashford to speak to Barcelona media, but when he entered the mixed zone area, where journalists speak to footballers, after winning his first league title, he looked relaxed, happy and, as he put it himself, "trying to enjoy the moment".

You could see why. This was the first league title of his career.

Equally, his intentions could hardly have been clearer. If he can stay at Barcelona, that's the place he wants to be, as he said himself he is "not ready for it to end".

He described Barcelona as "special", said they're going "to win so much in the future" and added that he'd love to be a part of that.

Some Barcelona supporters want Rashford to stay. Others haven't seen enough consistency from him.

With Raphinha sidelined through injury, Rashford has stepped up as a starter when needed. But with Raphinha now fit again and back in the side, the question is whether Barcelona value Rashford's impact off the bench enough to make his loan move permanent.
