Moyes, who’s known for crafting teams with strong defences, said: “It’s not nice. We work hard to make sure we’re defensively sound and I genuinely believe there’s no successful team that hasn’t got the best defence.
“Having that normally gives you a good chance of getting a result somewhere. At the moment we’re not as strong as we should be in some areas.
“We’ve hugely missed Declan Rice. I think Declan covered up a lot of things, was able to tidy things up and help us. He’s probably the best player in England at the moment, I would say.
“If you lose the best player in England out of your team, you’re going to be affected one way or the other – it doesn’t matter how good your signings have been and how well they’ve done. And by the way, a lot of things get talked about how much money we spend, but nobody talks about how much money we’ve taken in as well.
“Brighton have taken a lot of money in, but I think we’re probably right up there with the biggest ones that take money in as well.
“I always said, and I think everyone laughed, that Dec should have been £150million. Other players have been sold for close to that price and I don’t think they’ve touched Declan’s level of performance. The other thing is Declan is English, an England international, and he’s 25 now so he’s still got another six or seven years of his best years still to come.
