Brief Liverpool hope over a transfer for a thrilling forward has been quickly dashed after a double barrier surfaced, per a report.Liverpool are understood to be willing to sanction the exits of Divock Origi and Xherdan Shaqiri this summer. Shaqiri is on Lyon’s radar with an £8m move touted. Origi, meanwhile, would command a fee of around £12m, with a number of Premier League sides pondering moves.Should they leave, the Reds would be left dangerously short on depth in the forward ranks. That rings doubly true with Mohamed Salah and Sadio Mane due to miss a month mid-season at AFCON 2020.A glimmer of hope was found this morning when the Express indicated a Premier League flyer could depart.They claimed Watford’s Ismaila Sarr has asked to leave the Hornets, and Liverpool are known to be long-term admirers.Valued around the £40m mark, the Senegalese winger would fit the profile of players Liverpool like to buy.At 23, his best years are ahead and there is clear scope for Sarr to develop into an elite level forward in the coming years.However, the Watford Observer have emphatically put the kibosh on any Liverpool hopes. They state Watford have not received an approach for the forward, contrary to prior reports.But more importantly, they reveal that neither Watford nor Sarr would entertain a move this summer anyway.The Hornets remain ‘adamant’ Sarr is not for sale in the current window. Additionally, the player himself has ‘no desire’ to angle for a move at this stage in his career.Rodgers favourite to replace Arteta at Arsenal, while Howe waits in the wingsMeanwhile, a Liverpool star has seemingly given Jurgen Klopp a selection headache after his social media post hinted he is ready to return to action.Andy Robertson missed Liverpools opening contest with Norwich through injury after sustaining ankle ligament damage against Athletic Bilbao in pre-season.Klopp admitted Liverpool were lucky with regards to the Scots injury.

The left-back took to Twitter to post a picture of himself engaging in light training.Klopp reportedly personally intervened to reject transfer offers for Robertsons stand-in Kostas Tsimikas throughout the summer. And it appears his faith in Tsimikas could be tested as early as Saturday with a partially-fit Robertson now back in the mix.READ MORE: Liverpool transfer nearing completion for attacker with untapped potential
