"Huddersfield were the team to beat after winning three on the bounce, now we have won three in a row so we are the team to beat," Gerken told the East Anglian Daily Times.
"Coming from behind and winning just shows the mental strength this team has. It is a massive win and three wins in three puts us right up there near the top six. We have hit a real bit of form and have lost only three games in the last 14."
Next Saturday Mick McCarthy's side will take on Nottingham Forest at the City Ground.
