The Hatters led twice throughout the course of the ninety minutes, but the Blues quality was too much for Luton in the end, as they fell to a memorable 3-2 loss at Kenilworth Road.
Speaking after the game, Luton boss Nathan Jones said: “I’m realistically disappointed because I thought we could’ve been a bit braver sometimes in possession, but apart from that we came up against a top, top end Premier League side and we’ve given them a right game, and that’s all you can do really.
“We had ambitions of winning the game and we scored early, brilliant. We recovered from giving them the first goal, and score, but then they’re a fantastic side.
“You know they’re going to put you under pressure and you know you’ll have to defend really well, and we didn’t do that for the second goal. The third goal is wonderful. I can’t have any qualms with that. It’s top end movement that will cause the Premier League problems."
While a place in the FA Cup quarter-final wasn't to be, the race for the play-offs is still alive and kicking, and the Hatters will continue their efforts to consolidate a sixth place finish when they take on Middlesbrough this weekend
