Town boss Mick McCarthy says summer signing Jonas Knudsen has fitted in brilliantly since joining the Blues from his hometown club Esbjerg in the summer.
Danish international Knudsen, 23, was signed for a fee of around £325,000 in July and has now made 17 appearances for Town.
"I think he’s settling in really well,” McCarthy said. "He’s everything that TC saw in him and I heard when I spoke to the manager in Denmark and he gave me the heads-up on him. He’s just been a great lad, really tough, gets forward, he plays football, he can defend.
"I think for somebody who has just walked in the door he’s fitted in brilliantly, I’m delighted with him.
"Considering he’s £7.8 million cheaper than the one that we sold [Tyrone Mings], I think it’s not a bad deal, to be honest with you.”
The Blues manager believes there’s more to come from the left-back: "I see players coming into this country, into this league and into the Premier League from Denmark, from Holland, from Sweden and from other places and let me tell you it’s a helluva different ball game playing in the Championship to what he was used to.
"Poland, the same. Piotr Malarczyk, he wondered what was going on here. He thought he was playing with 20-odd whirling dervishes running around like Tasmanian devils, screeching and tackling and clattering into people.
"He really found that the intensity of training even was difficult. So when you come over and you’re going through that, are experiencing that, that’s difficult. And I think Jonas has handled it as well as anybody.”
