Mate, you're on the wrong track, simple as that. The data you're referring to is flawed by definition because it is solely based on the pre-match assumptions of journalists and not corrected afterwards if need be. I've watched over 50 matches of Sancho for Dortmund and lost count how many times the broadcasters and tickers listed him as starting on the right but he was found on the left from the very beginning. If you want to get a precise image, watch the heat maps. And Sancho's are looking like this:
Bundesliga 19/20
Bundesliga 20/21
Champions League 20/21
I'm not making this up, he is better on the left and played more on that side of the pitch. As I said, Favre and Terzic played Reus out of position to make room for Sancho on the left and now Solskjaer and Rangnick played him on the left preferrably, too. Do you think this is coincidence? He is a LW and most likely sees himself on that side of the pitch as well. And it's only logical because his skillset is much better suited to cut inside having the ball on his strong foot. It was a very brief period in which he played on the right and THIS was actually as a right sided 10 in a 3-4-3 with Hakimi not vice versa. He even made his first appearances for Dortmund as a LW and had one season in which he started on the right most of the time - and that was ith a very dominant RWB who is not comparable to any player you have in your squad. And if the media you consume suggests something different, it isn't very accurate with its facts.
