But this one is a tad more complicated.Signed for £146m just 18 months ago, the Brazilian has failed to live up to his price tag, and Spanish publication Sport believe that if Barca were to sell him, they’d want to recoup over half of that initial price (£86m).But which clubs will take the gamble, and have the money? Manchester United have been linked with the 26-year-old but would likely need to sell first.Coutinho’s agent has insisted Griezmann’s arrival does not mean the end for Coutinho at Barcelona but Spanish radio station Cadena SER say Chelsea will go in for Coutinho if they lose Eden Hazard and their appeal to the Court of Arbitration for Sport (CAS) for their transfer ban is overturned. Talking of Hazard…Philippe Coutinho’s Barcelona nightmare could be about to end.Source: AFPEden HazardOne of the longest-running transfer sagas could be decided early this summer, with no major tournament disruption and a personal decision “already made”, according to Hazard himself, even with the Europa League final still to come.Real Madrid are confident of signing the Belgian, according to Sky sources, with just a year left to run on his Stamford Bridge deal.If Hazard has told Chelsea he wants to stay, will the club attempt to cash in anyway? And if he’s told them he wants to go, will they fight to keep their best player with a transfer ban looming?It is unlikely anything will be decided before the May 29 final in Baku, and Real still may need to make room for Hazard in their front line…Gareth BaleEnter, Gareth Bale. His six years at Real Madrid seem to have gone in a flash, but it hasn’t all gone according to plan for the Welshman.Bought as Real’s centrepiece, Bale has shown flashes of brilliance and single-handedly won them the Champions League last season, but as he approaches 30, his future may lie elsewhere.Zinedine Zidane dropped Bale from his squad for Sunday’s defeat to Real Sociedad, and AS report there has been a “complete breakdown” in their relationship. Bale’s agent, however, says Bale wants to stay at the Bernabeu.Bale is under contract until 2022, so won’t come cheap. Tottenham could take Bale in a £10m loan but they’d have to pay around £250,000 of his wages. If Christian Eriksen was to leave Spurs, that may be viable, but otherwise a return seems unlikely.Manchester United and Bayern Munich have also been linked, while Le Parisien have reported PSG would go for Real trio Bale, Toni Kroos and Isco.Could Gareth Bale make a stunning return to the Premier League?Source: Getty ImagesPaul PogbaLess realistic than Hazard, but Real Madrid could be a destination for Paul Pogba this summer if he decides his time at Old Trafford is up, and particularly if United land Bale.A topsy-turvy season ended with an argument with a Manchester United fan and heavy criticism of his recent performances may prompt Pogba to seek out a move.However, L’Equipe reported this week Pogba’s wage demands do not fit in with Real Madrid’s wage structure, and Barca are unlikely to move for the World Cup winner.He still has two years left on his current contract and United have the option to extend it by an extra year.MORE FOOTBALL NEWS‘NOTHING REALLY PREPARES YOU’: Huge factor favours Sydney‘WE CAN OVERCOME ANY HURDLE’: Stage set for thrilling A-League GF THE RISE, FALL AND RISE AGAIN OF PERTH: How the Glory days returnedDavid de GeaIf United are to rebuild, money will be spent. Cashing in on Pogba is one option, but so too is David de Gea, the main character in perhaps the longest-running transfer saga in the club’s history.His current United deal runs out in 2020, but the Daily Mirror reported in March De Gea’s wage demands are too much for the club.Real’s No 1 Thibaut Courtois has only been at the club a year following his £35m move from Chelsea, but hasn’t impressed, and an interest has reputedly been retained in 28-year-old De Gea.This story originally appeared on Sky Sports and was reproduced with permission.
