Philippe Coutinho handed in a transfer request three months ago, according to Spanish news outlet El Pais.
The Brazilian forced a move to Barcelona through 18 months ago, with the Reds earning an initial £105million with the potential to make a further £37m in performance-related add-ons, as per the BBC.
His departure was taken badly by supporters but the phenomenal impact of Virgil van Dijk, Alisson and Fabinho masked Coutinho’s absence and the Reds have gone from strength to strength ever since.
Since Coutinho left the club, Liverpool finished on 97 points in the Premier League and made it to the Champions League final in successive seasons.
Jurgen Klopp, however, has yet to sign a new no.10 and with reports from Spain claiming the Brazilian handed in a transfer request three months ago, it might be the right time to move to re-sign him.
The report names PSG as one of several clubs interested in signing him and while Liverpool are not named, the Reds would be making a big mistake by not trying to sign him.
His ability to score from long range is a talent still unmatched at Anfield and while a return to Liverpool would create selection headaches for Klopp, his presence would mean the German would have a hugely balanced squad.
With players like Wijnaldum, Henderson and Fabinho, the manager has the tools to prevent opposition teams from scoring and in Chamberlain and Keita, the former Dortmund boss has players gifted at creating chances in transition.
Coutinho, however, has the X-Factor that makes teams worried in all kinds of attacking scenarios.
The one player that would suffer if Coutinho was re-signed would be Xherdan Shaqiri as his game time would take a huge hit as a result.
Of course, it would also strengthen Liverpool’s squad depth and take them a step closer to being able to challenge Manchester City in that regard.
