PSG football chief Luis Campos has taken aim at Chelsea over Hakim Ziyech's collapsed transfer last week.

The Moroccan midfielder looked all set to join the French champions until the end of the season, only for missed phonecalls and unsigned documents to delay proceedings until time ran out.

The French league rejected an appeal from PSG, and Ziyech was forced to return to London.

Campos is adamant the situation was the fault of the Premier League side, with the Ligue1 leaders not to blame as Ziyech was at their headquarters in France and had undergone a medical.

He said: "We had the player with us, we had done everything. But as with all transfers, you need all three parties to work well.

"In this case it worked very well for Paris Saint-Germain, it also worked well with Ziyech.

"Unfortunately, it didn't work well for the last party."
