Klaus Next summer we might be back in for him, depending on Gyokeres does and we might want to move Havertz on, Barca will be thinking about replacing Lewa. Maybe PSG might fancy a change up top depending on how Dembele does and then Bayern might be planning for life after Kane as he'll be 33. Liverpool as well will probably still hold a strong interest in him. Maybe Real Madrid will dump Vini Jr, put Mbappe on the left and need a CF as well.
Isak will be 26 next summer, top clubs will see him perfect as he'll be entering his peak and will have plenty of options.
