Former Schalke attacker Donis Avdijaj says turning down the chance to sign for Liverpool is the biggest mistake he has made in his professional career.

Avdijaj spent seven years with Bundesliga club, having joined at the age of 14 back in 2011 and progressed through the youth system.

Donis left on a free transfer to Willem II two years ago having featured in 12 games for the Schalke first-team.

The Kosovo international was released by the Dutch outfit in March 2019 and was snapped up by Trabzonspor that year, though he left a few months later to sign for Hearts in January.

The 23-year-old forward finds himself without a club again as his time at Scottish side has come to an end.

He admits his career could have gone another way as the PL champions and Real Madrid wanted him a few years ago.

Avdijaj told Sport1: “My biggest mistake, which I bitterly regret, was turning down another mega offer from Liverpool before I signed the long contract with Schalke, which was a matter close to my heart. I also had one from Real Madrid.”

Meanwhile, Liverpool reportedly have no intention of pursuing a deal for Napoli star Kalidou Koulibaly during the next transfer market.

Despite the Reds having being confirmed as PL champions, speculation persists that manager Jurgen Klopp is in the market for a new centre-half.

In recent months, the Merseyside side have been linked with an approach for Kalidou, who could be allowed to leave the club this summer.

However, according to Sky Sports News, Liverpool won’t be making a bid for the Senegal international during the coming months.
