Barcelona are to sue former player Neymar for £7.8m over an alleged breach of contract in the wake of his £198m move to Paris Saint-Germain.
The amount is understood to relate to a loyalty bonus Neymar received after signing a contract extension in October 2016.
“Barcelona decided to take these actions in defence of their interests, after a unilateral termination of contract urged by Neymar Jr a few months after signing the renewal until the end of the year 2021,” a statement read.
Brazilian striker Neymar said he was surprised by the decision but warned he is not going to give in.
The 25-year-old forward also informed that his lawyers are preparing a formal defense to the demands.
