I'm surprised by the preference for Dijksteel at right back. He's definitely more athletic and plays slightly better going forward, but pretty much every game he seems to get the ball caught under his feet or switch off at some critical moment that costs us.
I do think if you look at both Fry's and Dijksteel's number of bookings, it suggests they are either both utterly immaculate in everything they do, or not committed / aggressive enough to do what is needed at times to protect our goal.
Fry has 12 bookings and one red (which was a bit harsh) in 200 plus appearances. As a comparison Ayala has similar appearances for us at 216, but he has 48 booking (three doubles bookings, leading to reds) and two straight reds. Ayala also had 23 goals, Fry has two.
Dijksteel has 11 bookings and 1 red in 99 Champo games, four assists, no goals. Tommy Smith over his Champo career has 279 appearances, 7 goals & 31 assists. Discipline wise he's got 55 yellows and 2 reds.
I do think we lack commitment and aggression from our defenders attacking the ball, at both ends of the pitch.
