LEICESTER manager Nigel Pearson admitted it was a big wake-up call for his "lacklustre" side after seeing their 21-match unbeaten run in the Championship brought to an emphatic end in a 4-1 home loss to Brighton.
The Foxes may already have sealed promotion to the Premier League over the weekend but they still have the title to play for and would have been eager to continue their impressive form against Brighton.
However, a second-half brace from Leonardo Ulloa following first-half efforts from Dubliner Stephen Ward and Jesse Lingard set Brighton on their way to a big win at the King Power Stadium, with Leicester only able to respond through Gary Taylor-Fletcher's late goal.
Pearson said: "It was really disappointing to put on that sort of performance on what should have been an evening where we were celebrating getting promotion. So that's a big wake up for us."
Leicester's defeat allowed second-placed Burnley to close the gap between the two to six points with a 1-0 victory at Barnsley, although the Clarets' main aim at present is just to secure promotion.
They could do that this weekend if they beat Middlesbrough at Turf Moor and third-placed Derby lose at home against Huddersfield. Burnley's cause was helped by three of the four teams immediately below them losing last night.
QPR were beaten 2-0 at Blackburn, allowing Derby to replace them in third spot with a 3-1 win at Blackpool, while FA Cup semi-finalists Wigan and Reading, lost 1-0 at home to Millwall and 3-1 at Bournemouth respectively.
Those results have allowed a number of teams to close the gap on the top six, with Brighton, Ipswich and Bournemouth now just two points behind Reading.
Also last night, Leeds suffered an eighth defeat in nine matches after going down 3-0 at Watford on the day Massimo Cellino completed his takeover of the Elland Road club.
