Neymar could be tempted by a move from Barcelona to Paris St Germain, according to his agent.
The Brazil forward, 24, has excelled as part of Barca's 'MSN' strikeforce alongside Lionel Messi and Luis Suarez, with the Catalan club six points clear at the top of the Primera Division, through to Copa del Rey final and in the Champions League quarter-finals.
He also has a release clause in his contract of 193million euros (£154m), according to his representative Wagner Ribeiro, who nevertheless feels a "dream" move is a possibility.
Arsenal have an even bigger mountain to climb in Barcelona, where they trail 1-0 and 3-0 on aggregate in their Champions League last 16 tie.
The Gunners looked relatively comfortable for 15 minutes before David Ospina, deputising for the injured Petr Cech, made a superb save from Lionel Messi.
Minutes later, a lapse in concentration in Arsenal's defence allowed Luis Suarez to tee up Neymar for the opening goal, all but ending any hopes of an unlikely comeback.
It means Arsene Wenger's side must score three times without reply to pull off one of the biggest shocks in Champions League history.
Former Real Madird defender Roberto Carlos believes he could be key to taking Barcelona's Neymar to the Santiago Bernabeu.
The 42-year-old former Brazil international confirmed he was currently involved in talks to join new Real manager Zinedine Zidane's backroom staff at the Primera Division club.
The World Cup winner is confident he could persuade compatriot Neymar, who came third at Monday night's Ballon d'Or ceremony, to join Los Blancos from rivals Barca.
He told marca.com: "I had a meeting with Real Madrid about my future with the club.
"Soon I will know how I can collaborate with Zidane's Madrid."
While, regarding Barca striker Neymar, he added: "I can take him to Real Madrid. He's very young. I am sure next year he will finish even higher in the Ballon d'Or."

Brazilian forward Neymar will remain at Barcelona "for life" – so wishes the club's technical director Roberto Fernandez.
The 23-year-old underlined his status as one of the best players in his team last season when he scored 43 goals in all competitions as Barcelona won a Primera Division, Copa del Rey and Champions League treble.
Neymar is tied to the European champions until June 2018 and Barca recently expressed their intention to reward the Brazil star with a new deal that would make him the second highest paid player at the club behind Lionel Messi.
"We are currently working on Neymar's contract extension and I don't think there will be any type of problem," Fernandez said, as reported in Marca.
"I have no doubt in my mind that Neymar will spend the rest of his life at Barcelona."
Brazil captain Neymar has been handed a four-match ban, ruling him out of the remainder of this year's Copa America.
The Barcelona attacker has been punished for his role in Wednesday's post-game fracas, when he was shown a straight red card for confronting Jeison Murillo and Carlos Bacca after the Group C defeat to Colombia.
Brazil, who have yet to make sure of their place in the last eight, do have the right of appeal.
Bacca has been banned for two matches and fined $5,000 for his part in the melee.
Barcelona president Jose Maria Bartomeu, his predecessor Sandro Rosell and the club are set to stand trial for alleged "crimes against the Treasury and corporate crime" over the signing of Neymar.
Judge Jose de la Mata called for the opening of the trial on Wednesday and the three parties accused have 10 days to respond to Spain's National High Court.
The trial centres around investigators' allegations the club only declared that they paid €57million for the Brazil star when they actually paid "at least" €83m.
All three parties have denied any wrongdoing on several occasions.
