The 25-year-old has scored in three straight matches for Liverpool and deserves attention from Europe's biggest clubs.
The Reds managed to keep their Brazil global at Anfield beyond the summer transfer window despite Barcelona's numerous attempts to sign the number 10.
'We want to have the most competitive squad possible'.
Barcelona plan to reignite their interest in Philippe Coutinho in January and will test Liverpool's resolve with a £120million bid.
The Spanish club failed with three bids for Coutinho last summer, the last worth £115 million, with Liverpool standing firm there is no price that will force a sale this season. "We weren't going to give €200m or €150m - we made a decision to step away from such an expensive market, our offer was less than €100m, with add-ons it could have reached €120m". However, further claims state that his Nou Camp exit would only be approved if Barcelona offered a transfer fee that is deemed acceptable by Liverpool officials.
According to The Mirror, Barcelona are now ready to return for Coutinho in January after missing out on him in the summer. Liverpool's position has not changed and they are furious about Grau's comments. The Reds were unmoved when Coutinho officially asked him to be sold.
At this stage of the season, the hope will be that Coutinho ignores Barcelona's advances and continues to focus on his form at Anfield.
