True but it would be great to have 4 quality CBs all competing with each other for the starting spot. Plus Taylor seems to always get injured :/ Colo was also injured a fair bit last season which didn't help. Perch is a decent backup for DM, said himself he loves that position to run, nick the ball and give to kebab. But as a CB? nope dread when I see him or Williamson in the starting 11. Didn't Ashley or someone say CB and striker are the targets this summer?He is a back up back up CB though, Obviously Taylor, Mbiwa and Colo ahead of him. I'm not sure Douglas would be looking to join the club as a 4th choice CB on wages that are affordable for a 4th choice CB.
Perch has looked composed at CB when he has played there, he's cut out the mistakes from his game and is a good all round player. I'm not saying that CB is his best position, but as 4th choice cover he's better than spunking 40k a week on someone.
