Shiba is 20... relax mate, he has plenty of time to learn. Jack Reed was considered slow but played pretty well.I completely understand that Seibold wants roberts to improve his defence / bit more effort etc / maybe even is trying to get him to ask for a release.
I do think we need better centre depth next year if roberts leaves. Shibasaki, I dunno. sure he is alright in defence, but he is slow, makes a few mistakes and doesn't have much attacking threat about him at all.
Hopefully Roberts pulls his finger out and gets back in the team, or we release him and get someone else.
Yes would be nice to have Jimmy back, but he is widely inconsistent and it seems like pulls up with an injury or "soreness" after every game.
