He still looks to be set as our main left back for the season to come, so regardless if he is decent a few years down the line, next season we are both a little weak in that position.
Lets be honest, we have signed a left back from the same league who finished about the same place as Tranmere. Tranmere were in the top two for a long time last season and dropped away badly towards the end of the season. I'm sure he will do a job just as chiksen will do.
