It didn't matter when pogba and Sanchez signed for them.
They'll offer him massive wages as they are desperate for anybody half decent at the minute.
Different times though. Back then they were not in a big predicament they are now where top 4 is a major question mark. We dippers and spurs are pretty nailed on which only leaves a spot for rags Chelsea and arse.
Neymar is already on massive wages. He left barca to be the main man and not be in messi shadows. It kinda didn't work out for him in psg due to mpappe rising to be a superstar in his own right. But there is little chance of him wanting to go to the rags to play under a clueless manager in a team with the likes of smalling Jones and lingard while their main stars like pogba ddg and lukaku looking to bail the sinking ship.
Unless of course he has an unknown hard on for wanting to play in the PL then yeah he might go to the rags
