It's easily fixed, just normalize it by both teams time out of possession to get an actions per 90 minutes of defending.
United had 51% possession in the PL on average last season, Bayern had 59%. Still not perfect as I didn't check the possession stats for each players games, but still should be a better picture:
| de Ligt | Maguire | Martinez | Evans |
Tackles | 2,37 | 2,67 | 3,41 | 2,90 |
Interceptions | 3 | 2,78 | 1,41 | 3,02 |
Headed clearances | 4,73 | 6,02 | 2,27 | 4,20 |
Aerial duels won | 6,49 | 7,67 | 1,14 | 4,74 |
| | | | |
So he tackles less than all United defenders last season, but intercepts more (except Evans) and has more aerial superiority (except Maguire)
