Former Tottenham fullback Alan Hutton feels they can win a trophy this season.
But they will need to buy in January.
He told football.london: "I think it's going to be difficult to challenge for the league. The big thing for me is what they do in the January transfer window. If Ange gets funds to go and reinvest and they recruit well, I think we will be talking about them winning something.
"I think the culture of the club has changed, it's now more like if you score two, we'll score three. We've got talented players at the moment who can go and make something happen. I think they've gone through too many seasons now where it was very defensive-minded.
"Ange wants to win the ball back within the first five seconds and really put the team under pressure. I think the players have really bought into that and that's why we're seeing some great performances."
