Prolific goalscorer Lewandowki previously netted 12 goals in the first eight league matches of the 2019/20 season while plying his trade for Bayern Munich, while Harry Kane only managed to find the back of the net nine times in his first eight Bundesliga appearances after moving to the Allianz Arena from Tottenham last summer.

According to transfer guru Fabrizio Romano, Guirassy's release clause will be valid this summer, with Premier League clubs already showing an interest. And teams are expected to start their bidding for the Guinea international in July.

According to Sky Germany, Borussia Dortmund are now aiming to beat Premier League clubs to Guirassy's signature as they have made him a priority signing for the summer. But Stuttgart chairman Alexander Wehrle has explained to the outlet that the player is happy where he is.

"It was already clear last summer that he was leaving, and I already heard in the winter where he is said to have already signed," Wehrle said. "The fact is, he feels really comfortable. He is an undisputed leader for the first time in his career, he knows what he has in [Stuttgart manager] Sebastian Hoeness and the coaching team.

"He can now also play [in] the Champions League. That's another argument. For many it is clear that he is leaving, for me it is not at all clear. But we will sit down after the season."
