“Anyone really can beat anyone in this league, as shown when we went to Blackpool and didn’t really turn up.
"The character in our dressing room is unbelievable and we’re determined not to take our foot off the gas."
“In the past two games, though, we’ve shown who we really are and everyone has been fighting for each other.
“The character in our dressing room is unbelievable and we’re determined not to take our foot off the gas.

Ryan Williams bagged a brace at Portman Road on Saturday, while a shot from Curtis struck the woodwork.
The Republic of Ireland international said: “I don’t mind if I don’t score, as long as the team is playing well and we can get the three points.
“It was obviously a bit unlucky to see the ball come back off the bar, but I was happy for Willo for his two goals.
“He hasn’t scored that many, but he’s a great player who’s good with both feet and showed what he can do.”
