Neymar is to fight a claim by Barcelona for compensation following his move to Paris St Germain and has also promised to battle his old club for part of his 2016 contract renewal premium which he claims has not be paid.

The Brazil forward left the Nou Camp this month for a world-record £200.6million, joining PSG in a move that more than doubled the previous highest fee.

The Spanish club said on Tuesday they were pursuing damages from Neymar for what they allege to be a "breach of contract".

Neymar's response is the latest move in an increasingly bitter war of words following his move to France.
