Well, Trent is down as a right back on any team sheet but he spends most of his time in midfield areas, whether wide or just inside.
When he produces the goods in attack, him being further forward isn't a big problem.
When he doesn't, all he does is find himself too far up the pitch, leaving acres of space for teams to attack. It's a weakness that every team should know about.
It's something that you have to accept with him in the team.
