While Trent may not be the so good at defending, I know he can defend and I have seen him defend.
I am no coach but something tells me that his attacking outputs lead to him being told not to get involved in serious defensive works like tackling. So as to not get injured.
Take other fullbacks who are both productive in attack and defense as an example; James, Walker, Chilwell, etc. they always need to visit the hospital due to injuries.
Or maybe it's because I'm a die hard fan of Trent.
Well, we are at the top of the table. What a good time to be a Liverpool fan.
