( CNN ) -- European champions Barcelona claim they will sever ties with Real Madrid if their fierce Spanish rivals continue to push the `` bounds of sportsmanship . '' The two clubs faced-off five times over the course of last season , culminating in two tempestuous Champions League semifinals in which players from both sides clashed on numerous occasions . Real coach Jose Mourinho was handed a five-match ban by UEFA after comments he made after the first leg of the tie , in which he claimed match officials favored Barcelona . He was also sent to the stands during the game at Real 's Bernabeu stadium after criticizing the referee . Arsenal captain Fabregas : My future still to be decided . Real then claimed Barcelona 's players had play-acted to con the referee , and that Sergio Busquets made racist comments to their Brazilian defender Marcelo -- a charge UEFA later dismissed . In a press conference on Thursday Barca president Sandro Rosell warned that his club would break ties with Real if next season was again punctuated by poor relations . `` Real Madrid and FC Barcelona are ancient institutions with many supporters and aficionados , '' Rosell said in a statement on the club 's official web site . `` Real Madrid crossed the line of acceptable sporting rivalry by making accusations against our club without any foundation . `` If the limits of fair play are passed once again , we shall be obliged to end our institutional relations , something we have absolutely no desire to do . `` The rivalry will continue next season but we will not allow them to go beyond the bounds of sportsmanship . '' Rosell also made reference to the `` numerous provocations '' made by Mourinho , pointing to the post-match press conference that landed him in hot water . The Portuguese this week appealed against his ban . He said : `` Comments by the protagonists have always served to enrich footballing debate . But this season a Real Madrid employee , its coach , also went beyond all the limits of necessary sporting rivalry . `` He even went as far as to say that our coach should feel ashamed of some of our victories . The press conference given by the Real Madrid coach after the first leg of the Champions League semi finals at the Bernabeu would certainly have made any sportsperson feel ashamed . `` He accused our club of having won titles thanks to some kind of national and international conspiracy , implicating in this conspiracy the good name of Unicef and the football authorities . '' Barca 's president went on to claim the club 's season was the best in its history , after coach Pep Guardiola secured the Spanish league title to go with the club 's fourth Champions League triumph . Rosell also hinted that Barcelona would be willing to spend big if the right players became available , as speculation over Arsenal captain Cesc Fabregas ' future continues to grow . `` We 'll see what happens in the transfer market . Initially , we have $ 63 million but we might use part of next year 's money too , '' he said . `` Guardiola has his preferences , but he does n't talk about names , he talks about positions that should be strengthened . `` Cesc ? I guess he 'd like to join us , like a lot of players would , but we wo n't go mad and offer silly fees . Last year we offered $ 56 million for Cesc , this season his value is less . What we can offer will also depend on his salary . ''
