Fifa president Sepp Blatter's plan to cap the number of foreigners allowed to play for a club is impossible, his UEFA counterpart Michel Platini said.

European soccer's top official said he backed the 'philosophy' behind Blatter's scheme to limit the number of foreigners in a starting line-up to five from 2010.

But Platini said world soccer's governing body needed to accept the plan could not work in the European Union due to laws which allow free movement of labour.

The philosophy is fantastic but legally it is difficult." said Platini.

"I can understand FIFA because they have 208 national associations and then there are 29 (EU members) who are all in our confederation. The philosophy is good but for me it is not possible."
