A Spanish court has asked Chelsea, Real Madrid, Bayern Munich and Manchester City to detail past bids for Neymar.
A host of top European clubs have been asked by the Spanish National Court to disclose their bids for Neymar as part of investigations into the Brazilian's move to Barcelona.
The Spanish champion is already set to stand trial over allegations of a misappropriation of funds in relation to the signing of the former Santos man in 2013.
The 23-year-old was officially signed for 57.1 million euros but it was later claimed that the total cost was around €95.
