French World Cup winner Bixente Lizarazu doubts PSG are serious about signing Liverpool ace Philippe Coutinho.

The midfielder is being linked with PSG and Barcelona ahead of the January market.

However, Lizarazu reasoned to Telefoot: "Coutinho is a great player with an excellent shot and passing quality. And what's more, I think he's not fully mature.

"He can still be much more consistent and physically stronger. But (Julian) Draxler is a great player. PSG can continue with him and especially it is necessary to step back for financial fair play.

"Coutinho, he will cost more than €100m. So the economic parameters are problematic and I think it is not a priority today for PSG."
