As you point out though, Son seems to contribute when Sessegnon and/or Davies start.That’s like mentioning the Bale curse back in the day, it stems far beyond just one player. AVB would also be our 3rd best manager in history if we went by percentages.
Son has been poor and subbed off in a large number of games Sessegnon has also started so there’s no genuine correlation Son actually plays well Sessegnon starts. One or both generally get subbed when they start together too, which further implies there’s no genuine link up or partnership between the pair.
Davies I’d agree with you on though, he’s been by far the best LWB this season in his small amount of games.
Perisic seems to be the contributing factor to him not playing well.
This would also appear to be the case last season, when Reguilon and Sessegnon played there.
Son won the Golden Boot and now he's playing badly and people think he should be dropped.
