Alex Telles contributed 26 goals and 57 assists during his four years playing for Porto. That record is outstanding for a left-back but it's made less impressive when noting 16 of those goals were penalties. His highlight reel is mostly from the 12-yard spot.
Manchester United thought they were signing a left-back that was accomplished going forward when they signed Telles for £13.8m in October 2020. They were actually signing a penalty merchant and a left-back that couldn't defend. There have been almost two years since Telles' arrival and it's been clear for some time now that he's well below the level required to play for the club.
There wasn't much seen of Telles in his first season at Old Trafford. Luke Shaw responded to the new competition with genuinely world-class performances and that ensured Telles' involvement was limited. He quickly became accustomed to the bench.
