Porto will insist on top price to sell Yacine Brahimi.

The Algeria midfielder is interesting Manchester City and PSG, among several European heavyweights.

AS says Brahimi's Porto deal includes a clause entitling former club Granada 10 per cent of any sell-on fee.

For the moment, Porto have referred the likes of City to the midfielder's €50 million buyout clause.

Brahimi joined Porto last year from Granada for €6.5 million.
