Aguero 'delaying' Barcelona switch 'until he knows Lionel Messi is STAYING'

Sergio Aguero is adamant that he will not officially sign for Barcelona until he knows whether Lionel Messi will stay at the club, according to reports.

Manchester City ace Aguero looks set to move to the Nou Camp this summer as a free agent and there were even indications that he would undergo his medical on Monday - just two days after the Champions League final.

But the situation now looks to have become more complicated with Mundo Deportivo claiming that the green light will only come from Aguero when the future of talisman Messi is clearer.

The deal for Aguero to join Barcelona looked to have been sealed with the terms of his contract agreed and City emotionally confirming his departure after a trophy-laden decade of service.

His friendship with Messi is a potential snag, however, with Aguero believing that they would work well together on the pitch and fit in alongside the mercurial superstar's dazzling playstyle.

Barcelona president Joan Laporta admitted recently that discussions with Messi over a new contract are 'going well', but no agreement has yet been reached.

The precarious situation leaves Barcelona in the lurch after a disappointing campaign, which may also see Ronald Koeman leave this summer, and Aguero was earmarked as the first big-name addition to spark a recovery.

It is believed that Aguero's camp have told Barcelona that they are keen not to rush into a final decision although the club still remain confident that the switch will get across the line sooner rather than later.

However, despite the Catalan outfit confident that it is just a matter of time, there are a number of other clubs interested in swooping in to snap up Aguero.

A host of unnamed Premier League teams are thought to have pushed for the veteran ace in recent days, and Juventus are also keeping a keen eye on City's all-time record scorer.

The same outlet add that Aguero's priority is to take up the next chapter of his career at Barcelona alongside compatriot Messi - but his potential other suitors are hopeful to steal in.

It has not been entirely ruled out that Aguero will have his medical checks in Barcelona and put pen to paper early next week, before then linking up with Argentina for the Copa America.

Mundo Deportivo say that these developments would suggest Messi is closer to agreeing to remain at the club.

Fresh from City sealing another Premier League title this month, a teary Pep Guardiola revealed that Aguero was 'close' to joining Barcelona and admitted that the champions 'cannot replace' the striker.

Aguero signed off in the top-flight in typically devastating effect, having netted a brace in the 5-0 win over Everton and come close on several occasions to notching a memorable hat-trick.

'We love him so much,' Guardiola told Sky Sports. 'He is a special person for all of us. He is so nice, he is so nice. He helped me a lot, he's so good.'
