Markovic was loaned out at the start of the season.
Markovic was loaned out to Turkish side Fenerbahce at the start of the season by Klopp's predecessor Brendan Rodgers after the Serbian had a tricky first season at Anfield following a £20 million arrival from Benfica.
However, with the Reds going through an injury crisis right now, and the Reds pretty thin on the ground when it comes to wide players in general, it is thought that Markovic would have proved useful at this stage of this season, in hindsight.
The Express reported in October that Klopp doesn't have the option to recall the Serbian this month, and with Ryan Kent, Sheyi Ojo and Tiago Ilori all being recalled from their loan spells in recent days as the injury crisis at Anfield has taken hold, it's hard to think that Markovic wouldn't have been in Klopp's thinking.
Klopp is quoted in the Echo, saying: “It would be too easy to say ‘no, I would not have done things like this and given him out on loan'.
“But I was not in the situation so I cannot say too much about this.
“There would have been good reasons for this. I don’t think we can take him back.”
Rodgers was never really convinced by Markovic as he was used in a variety of positions and never really given a run in the side in one role and it did nothing to help him settle into life on Merseyside.
There were flashes of quality in some performances, along with the three goals he scored for the side, but Klopp seems keen not to criticise situations he wasn't privy to. However one gets the feeling that with his recent comments about youngsters going out on loan, Klopp would've preferred Markovic to have been available for him at Anfield.
