Real Madrid, Barcelona battle for Chelsea's Robben.

Real Madrid and Barcelona are going head-to-head for Chelsea winger Arjen Robben.

Both clubs are in the market for a new left-sided midfielder and have penned Robben at the top of their shopping lists, says DiarioSport.

Robben is weighing up his future at Chelsea, particularly with manager Jose Mourinho now staying on next season. The pair haven't seen eye-to-eye this term over Robben's injury record, though the Blues boss was full of praise for the winger over the way he performed on Tuesday night at Liverpool.

Robben was promised to Real fans by Ramon Calderon as he battled for last summer's presidency and remains a target for the Madrid club. Barca coach Frank Rijkaard, meanwhile, is a big fan of his fellow Dutchman and is convinced his versatility would fit well into his playing system.

According to Jose Mourinho, there are going to be changes at Chelsea in the wake of their Champions League semi-final exit earlier this week. The possibility that the likes of Lampard, Carvalho, Essien and Robben could be up for sale is reported to have aroused the keen interest of Real Madrid and Barcelona.

After failing to lure their top two targets to the club (Cristiano Ronaldo and Kaká), Real Madrid are likely to renew last summer's unsuccessful bid to sign Arjen Robben, who is very reasonably priced at €18 million euros.

However they could face competition from their Catalan rivals, who are also rumoured to be interested in signing Essien and Lampard to reinforce their midfield while Frank Rijkaard is also said to be interested in Portuguese defender Ricardo Carvalho.
