After the first season with us Martinez wanted to develop the training ground and youth development side of the club. He wanted to put in "homes" so the players could stay overnight rather than go back to their families for some training sessions I think.
Agree with
@BigDunc9 though that something is annoyingly wrong. I expect we will see a signing or two before the window closes but nothing major like we saw with Lukaku last season. We have spent the least amount in the league so far and although we have strengthened pretty well so far it's still a little worrying - though spending for the sake of it isn't something I'd want to do either.
