Sorry but this doesn’t make sense, as in one paragraph you say he wants to see/judge what Arne is about then you say if he takes him off it would damage that friendship/respect.
Trent has always stated that he loves Liverpool FC, surely by not taking him off when he was having his worst game then that would be detrimental to the Teams chances and therefore Arne would lose Trent’s respect, because he didn’t make the right decision for the team.
If you love a team, then the Team’s performance and result comes 1st.
Or do you think that Trent thinks that he comes before the Team?
