Ipswich Town's on-loan defender Danny Collins says the club "fear no-one" in the Championship.
The Blues have recorded three wins from their last four games, keeping three clean sheets along the way.
Collins told BBC Radio Suffolk: "We don't fear anyone in the league. Look at the squad, there's a lot of Premier League experience, a lot of quality.
"We've changed our formation these last few games and teams are struggling to cope with us."
He added: "The lads in front of us have started to click and it's a joy to watch at times.
"We look like adding goals to our good performances which is nice."
Collins, 31, is on a three-month loan deal from Premier League side Stoke City and has not ruled out the possibility of extending his stay at Portman Road.
"I'm enjoying it, overall I've been pleased with my performances," he said.
"Hopefully we can get something sorted out to stay here longer. We'll have to see what happens."
First-team coach Sean McCarthy echoed Collins' sentiments about Town's up-turn in form.
"There's a confidence, a feel-good factor at the club that comes from winning," he said.
"The players that we've brought in are starting to gel now.
"Everything feels good around the place at the moment, the players are enjoying themselves."
Ipswich travel to fellow promotion hopefuls Cardiff on Saturday with both teams just one point outside the play-off places.
