There should be a long line of clubs queuing up to sign Neymar from Paris Saint-Germain this summer, but despite being one of the world's most recognisable footballers -- and one with an incredible goal-scoring record to justify that billing -- the Brazil forward has become the superstar that nobody seems to want.

Financial realities and changing football philosophies have conspired to make signing the 30-year-old something which makes little or no sense to every club that could afford him.

Due to the terms of the three-year contract Neymar signed at Parc des Princes 12 months ago, an automatic 12-month extension to his deal will be triggered on July 1, so it would appear that he is committed to the French champions until his mid-30s.

But it has become an open secret within the game that Neymar -- still the world's most expensive player following his €222 million ($264m) move from Barcelona in 2017 -- is available for a loan or permanent move during this transfer window, with sources telling ESPN that PSG would happily offload his €700,000-a-week ($730,000) wages due the financial burden of paying Kylian Mbappe -- who himself signed a new three-year deal last month after appearing to be set for a free transfer to Real Madrid -- and Lionel Messi to be at the club.

Despite the huge wealth of PSG's Qatari owners, there is still a need for the club to project the image of being run as a viable business, so reducing the wage bill is a necessity, but Neymar's fitness record over recent seasons and his difficult relationship with the team's past two coaches, Thomas Tuchel and Mauricio Pochettino, are also factors in PSG's willingness to listen to offers for the player.

Sources have told ESPN that Pochettino became hugely frustrated with what he perceived to be the soft treatment of Neymar by the club's hierarchy when the former Tottenham Hotspur coach wanted to impose firmer discipline and introduce stricter rules about off-field conduct. Tuchel, meanwhile, struggled to get the best out of the player having adopted a blunt and honest approach to motivating him.
