he's the best one on one player at taking men on and beating them in the division, and it's not close. he had 50 more successful dribbles than the next player in the league. he's got the third most successful dribbles per 90 in europe.
on a well-coached team, the best dribbler in the league would not play in teh system nuno devised.
i'm not saying he's a bad coach, but it's not an uncommon thing when a coach leads a club out of the lower divisions and fails to improve the side in successive seasons in the top division. the premier league is just really tough.
a -15 goal differential, when the next three clubs ahead of you in the table are +8, +6, +14 sort of flatters you as well
only twice in the last 9 games did they even have a single expected goal, and those two games were home to sheffield, where they managed 1.23 xG and away to west ham where they managed 1.96 in a 3-2 loss.
from open play, their xg differential on the season was -10. that's relegation level.
