I am still annoyed at Ederson's booking v Arsenal, so I conducted a non-scientific experiment by looking a some goalkeeper bookings. The two with most bookings (5) are Martinez (Villa) and Pickford (Everton). I used the live text match data from the BBC website but this doesn't give the reason for the booking, however I don't think that it's a leap to presume that (most of) these bookings were for time-wasting given the score in the game. This is what I found...
Martinez 5
88 v Man U won 3-1
90+2 v Leeds won 2-1
90+8 v Brighton won 2-1
84 v Arsenal lost 4-2 (booked at 2-2)
77 v Everton won 2-0
Pickford 5
81 v Brentford drew 1-1
90+6 Liverpool drew 0-0
90+5 Saints won 2-1
86 Arsenal won 1-0
87 Liverpool lost 2-0
I have shown Eddie's for info
Ederson
36 v Arsenal won 3-1
83 v Spurs lost 1-0
