"Mason is getting closer really," explained Carrick. "He’s on the grass and getting closer, looking at being around training soon.
"[We've] just had to be patient and he’s a good player, so we’re making sure he’s ready. The good news is he’s getting really close.
"Matthijs, he’s had a back issue which has been slower to progress. It's something we’ve been working through and he’s getting there. He’s in the right direction but just further behind.
It’s part of football unfortunately, so we’ll get him back when we can. It's just the nature of the issue really. It’s a difficult one to pin down a timeline. He’s definitely improving, so we're just working towards that really. I can’t give you more at this stage."
