Neymar, Thiago Silva, Bale and the future Clasico stars Barcelona & Real Madrid could sign this summer

Although Barcelona and Real Madrid both go into the concluding weeks of the 2011-12 season scrapping for major honours, neither side will want to be caught cold in the summer transfer market, which could dictate the long-term success of both clubs.

Coaches Pep Guardiola and Jose Mourinho are well aware that their squads are not yet perfect – a fact rammed home by the pair of midweek Champions League defeats the teams suffered. And for weeks, months and in some cases perhaps even years, the two Spanish giants will have been plotting their forthcoming transfer targets, who will be acquired in order to maintain the prominent position of the clubs both domestically and on the continent.
