Is this a fact free zone ? I keep reading statements that are quite clearly incorrect if you look at the data on Fbref, WhoScored and Understat (links below).
Brighton are a passing team. The player on the ball has lots of options to pass the ball to. They create a fair amount of chances but their finishing has been terrible this season.
Bissouma's pass completion rate is 86.8%. Which is marginally lower than both Fred and McTominay. For short passes Bissouma 40.9 (accurate) v 4.8 (inaccurate). Long passes 2.3 (accurate) v 1.8 (inaccurate). McTominay Short 43.4 v 5. Long 2.8 v 1.6.
Perhaps Bissouma attempts more ambitious passes ? 0.4 key passes per 90 mins. Again below that of Fred and McTominay. His xA90 is 0.03 this season, was 0.01 last season, 0.05 the season before. He has 0 assists in the PL in 3 seasons. McTominay 0.8 key passes per 90 mins. xA90 0.11, 1 assist this season. Fred 0.9 key passes, 0.09 xA90
Progressive passes per 90 mins: Bissouma 3.38, McTominay 4.61, Fred 5.73
Progressive carries per 90 mins: Bissouma 4.04, McTominay 5.47, Fred 4.39
He's good at shooting: no he isn't. His shot map is awful. A huge percentage of his shots have been off-target. He has scored 2 goals in the PL in 3 seasons. Shots inside the area: 3 saved 1 blocked 8 off-target. Shots outside the area: 2 goals, 8 saved, 18 blocked, 36 off-target.
Bissouma has one red card this season in the PL, after 89 mins in the 3-0 win against Newcastle so didn't cost them.
I'm not suggesting for a moment that Bissouma isn't a good player but if you think he'd come in and be an automatic upgrade on Fred or McTominay, I suspect you'd be disappointed.
