Harry Redknapp remains baffled by the "few idiots" who jeered Tottenham at half-time against Fulham.
Redknapp was angered by some fans at White Hart Lane on Wednesday who showed their displeasure during the interval of Spurs' FA Cup quarter-final replay against Fulham.
The hosts were trailing at the break but fought back to book a semi-final date at Wembley with Portsmouth thanks to a 3-1 success and Redknapp has criticised the supporters who booed midweek.
"I don't know what anyone could come to Tottenham to boo about because they've seen football this year that has been out of the top drawer," said the Spurs boss, whose team are also in pole position to land the coveted fourth UEFA Champions League spot.
"If you want to be entertained, come and watch Tottenham play.
"You always get people who don't understand the game. You could be playing badly and winning 1-0 and they don't moan.
"They see the scoreboard and react because the team are losing. 99 per cent of the fans are fantastic; it's only a few idiots.
"It's happening all over the place at the moment. It's happened to Martin O'Neill at Aston Villa in recent games if they haven't been ahead at half-time."
Spurs' progress this season has come despite a long injury list which was extended when Vedran Corluka picked up an ankle injury against Fulham.
The Croatian joins Ledley King, Jonathan Woodgate, Aaron Lennon, Jermaine Jenas and Jermain Defoe on the sidelines and Redknapp revealed Jenas has encountered problems in his rehabilitation.
"JJ has had a bit of a setback," said the 63-year-old. "He is sore and has had to take a backward step. He's still getting a bit of pain after the hernia operation."
Tottenham meet Portsmouth in the league this Saturday in a dry run for their FA Cup semi-final with Pompey looking doomed to relegation after incurring a nine-point deduction for going into administration.
But Redknapp believes his former club, who he guided to Wembley glory in 2008, will be back in the top flight eventually.
"They've been in the bottom division and come back," He added. "When Milan Mandaric came in the doors were locked for business, they've been there many times before.
"When I was there they had no training facilities. I had people like Teddy Sheringham and Paul Merson training where Sunday teams had played.
"Hopefully they'll find a new owner who cares and get them back up again."
