What is the point of this comparison? Is there any doubt that Sancho has been reaching world class levels for two seasons straight at Dortmund? Any team would be lucky to get him. But his price will definitely be over a 100m and his wages will be pretty huge to. There is a lot of competition from United and Real for him as well. Coming to Kai, he also has amazing numbers for his age. And he has played mostly in the midfield for a large part of the season as well, unlike Sancho who has been on the wings. Dortmund are a far more attacking team as well. Kai will be easy to get now since Bayern are out of the race it seems. And going by his social media interactions, he does want to come to Chelsea. Kal suits us more right now since we have already signed a RW and Kai can play in almost every attacking or midfield position. He might be that missing creative spark in our midfield. Or might be a perfect partner for Werner. Its all upto how Lampard uses him.
