Barcelona think Liverpool and Manchester United target Marco Reus has already agreed terms with Bayern Munich to move to the Bundesliga giants next season, reports in Spain claim.

The German international's future at Borussia Dortmund has been under scrutiny in recent weeks after it was revealed he had a special release clause in his contract which allows him to leave the team next summer for as little as €25m (£20m).

Manchester United, Liverpool, Arsenal and Atletico Madrid were said to be monitoring the situation while recent reports in Spain claimed Barcelona had also joined the race to secure his services.

After being banned by Fifa from making any signings for a year from January 2015, the Catalans are considering going on a 'spending spree' before the end of the current transfer window in order to bolster their squad, not just for this season but for the next, when they will be handicapped.

Having already signed Luis Suarez from Liverpool the Catalans were not planning to make any other marquee additions this summer but the ban has forced them to rethink their plans. recently both Mundo Deportivo and Sports suggest they were considering to signing Reus, then loaning him to Dortmund until next season.

However, Mundo Deportivo now claims that the Catalans suspect they have arrived too late in the race for Reus.

The report also says Barcelona have the feeling that the German star has already committed to Bayern in order to join them next season – with Pep Guardiola's side keen to match his then €25m buy-out clause to finalise the deal.

Bayern have already signed both Mario Gotze and Robert Lewandowski from Dortmund in the last two years and club president Franz Beckenbauer recently fuelled rumours of their intention to buy the player.

"I can imagine him at Bayern very well. If you can get a player of his class, you need to try it. If he doesn't go to Bayern in 2015, he will probably go to another big club like Real Madrid or Manchester United."
