Adam spoke after their 2-2 draw with Manchester United.
“Expensive free transfers,” he said. “Kurt Zouma has come in on probably good wages from Chelsea. Fletcher, Choupo-Moting, free transfers on good wages, Jese from PSG. It doesn’t look like we’ve spent a lot of money on signings but we have on wages and agents fees. That’s just the way the game is.
“We have to be clever because we can’t compete with the top ones. Everton have spent £150m, £160m and we can’t compete with that. But we know that anybody at Stoke we can beat them on our day.”
