The arrival of Fabinho is evidence that Liverpool boss Jurgen Klopp is busy working to improve his squad.But the German has another matter to think about - the players that have returned to the club from loan spells.Daniel Sturridge, Divock Origi and Lazar Markovic were among those to be loaned out, with various degrees of success.One man who benefitted from his time away from Anfield is midfielder Marko Grujic.The 22-year-old was loaned out to Championship outfit Cardiff City in January and he would do enough in his 14 appearances to earn a spot in Serbia’s World Cup squad.Cardiff also secured promotion to the Premier League, so it was a successful season for the Bluebirds.Now, Klopp has to decide what to do with Grujic.

Liverpool's plan for Grujic

Fabinho and Naby Keita’s arrivals are a problem for the midfielder and according to the Mirror, Liverpool plan to send him out on loan once again.

Cardiff manager Neil Warnock is reportedly a “big fan” of the Serbian player and could attempt to re-sign him for the 2018-19 campaign.

With Fabinho and Keita added to a midfield group that already includes Jordan Henderson, Alex Oxlade-Chamberlain and Georginio Wijnaldum, it makes sense for Klopp to send Grujic out on loan again.

He would find regular football incredibly difficult to come by at Anfield.

The news has got Liverpool fans tweeting.

Some would like to see Grujic given an opportunity in the first team, even if he's used as a squad player.

Others think a loan move to a Premier League club would be wise.

But Twitter user @jivk3 wonders whether Liverpool even need to keep Grujic.

There is still a hope that Grujic has a future at Anfield.

He was one of Klopp’s first signings, arriving from Red Star Belgrade in 2016, and the Liverpool Echo claim Grujic is rated by the club.

Grujic will have learned a lot under Warnock, who he claims is similar to Klopp.

"In some respects they’re really similar and have really good relationships with their players," Grujic said in March.

"They try to send their passion to us. I learned a lot under these managers, the two styles of football is different but as a young player you need to learn as much as you can."

Grujic’s immediate future will become clearer after the World Cup.

Regardless of what happens, a move to Cardiff would ensure he gets to stay in the Premier League.
