Ipswich manager Roy Keane admits his side were given a stern test in the Tractor Boys' 2-1 victory over Sheffield United.
Tamas Priskin gave the Blues a sixth minute lead, and although Stephen Quinn levelled for the Blades, Gareth McAuley's 40th minute strike from close range proved to be the winner.
Keane said "It's a pity we couldn't build on our good start. The first goal is always vital in any game but (our start) was a bit better.
"It was a tough game, a really tough game. They put us under a lot of pressure but we managed to hold on and grind out a result without being spectacular - but you have to take that away from home.
"There were opportunities for us to be a bit more clinical and finish the game off but credit to Sheffield United as they put us under a lot of pressure.
"I think we rode our luck a little bit but we all need that in football. With Sheffield United having suffered a couple of defeats, sometimes you just don't get the run of the ball and sometimes football can be so frustrating."
