For one reason or another Neymar is not playing for Real Madrid Neymar will line up for Paris Saint-Germain for their Champions League round of 16 clash with Real Madrid, the Brazilian star could however have been signed by the Spanish side on numerous occasions.Here are five times the Madrid could have made a move for the Brazilian1. 2006: On trial at Real MadridIn 2006 Neymar played his first game on European soil, as he went to Real Madrid on trail with their Juvenil A youth team for two weeks. Madrid’s youth coaches were impressed by the young Neymar, but there was a reluctance to fork out a estimated the €60 million asking his agent Wagner Ribeiro demanded.2. 2011: When he renewed with SantosEven though Madrid failed to sign him after the trial, there was already an established relationship, and with Florentino Perez back as president there was an opportunity to sign him before his renewal. Spanish paper, Marca and AS both claimed personal terms were agreed for the Brazilian, only for the move to break down due to how the money was to be shared among third-party investors.Neymar went on to sign a new contract, extending his stay until after the 2014 FIFA World Cup.3. 2013: Before he joined rivals BarcelonaBefore 2012 Barcelona were not strong favourites to sign Neymar, however a reported secret “advance” of €10 million, was agreed with his father Neymar Senior. Madrid instead negotiated with Santos as Barcelona had the upper hand, even though Perez was willing to offer an €11 million yearly wage and pay a world record fee of €100 million for the Brazilian at the time.He opted to join rivals Barcelona and said “I’m really pleased these two great clubs both wanted to sign me, but I followed my heart, and here I am. We received offers of more money, but it is not just a question of money.”4. 2016: Renewal at BarcelonaEven though he signed for arch-rival Barcelona, Neymar continued to be linked with a move to the Spanish capital.The heavyweights in the Madrid board were making moves underneath to recreate a move similar to Luis Figo’s transfer. There were inquisitions into the legality of his move from Santos to Barcelona, as the Catalan club accused Madrid for starting the investigations.The opportunity to sign Neymar would however presented itself when his contract was due renewal and his father was listening to offers from potential suitors.Neymar would however sign a new contract which kept him at the club for another season, but with a release clause of €222 million5. 2018: Summer Transfer?Neymar moved to PSG from Barcelona after his release clause was activated and he showed desire to make the switch to France.The Brazilian star was not going to switch clubs in the January transfer window, as it will rule him out of the transfer window and more so when drawn against Madrid in the Champions League.Madrid are not in contention for the Spanish La Liga and are also out of the Copa del rey, and there are hints of a major reshuffle at the Bernabeu, which could see Neymar replace 33-year-old Cristiano Ronaldo at Madrid. Madrid left back and Neymar’s compatriot Marcelo said, “It would be great if Neymar came to Madrid, and I believe he would fit perfectly into the team.”While Neymar’s teammates at PSG have admitted the he could leave, Thiago Silva said “I do not know,” “I cannot speak for him. I will say this: that I hope Neymar stays with us.”If Neymar will move back to Spain time will tell, However there is a continuous interest in the Brazilian and an opportunity to sign him will present itself.
