Andre Villas-Boas admits his team put on their worst performance of the season as Tottenham slumped to a shock 1-0 defeat to strugglers Wigan at White Hart Lane.
Tottenham went into the game having won five of their previous six Barclays Premier League matches, but they struggled throughout the clash. Wigan goalkeeper Ali Al-Habsi was a spectator for much of the encounter in north London, and Villas-Boas' men were very fortunate that Ben Watson's strike was the only goal they conceded.
The performance, which drew an outcry of anger from the home fans - who also disagreed with Villas-Boas' decision to substitute Jermain Defoe - was way below what the Portuguese expects. "It was maybe our worst performance of the season," said Villas-Boas, who saw his team booed off against Norwich and West Brom earlier in the campaign.
"We didn't manage to keep the ball or pass well. We couldn't recognise ourselves today. Wigan were superior. Our chances weren't clear cut. There are various reasons why we played like this. The opponents were sharp and aggressive. We kept making mistakes. We played more with the heart rather than the head."
The home support, who were already angry at their team's showing in the first half, turned on their team's manager moments after the goal went in when Villas-Boas took off Defoe and brought on Emmanuel Adebayor to partner Clint Dempsey up front.
The Spurs fans booed the decision and chanted Defoe's name as he sauntered off the pitch before grabbing his coat and disappearing down the tunnel. Villas-Boas explained the decision to the in-form striker afterwards, and insisted he understands the fans' angst.
"We understand that they can show their frustrations," the 35-year-old said. "We don't do things to punish them or for the fans to show revolt. We do things for the benefit of the team. They want the win, but we want the win as much as them. We respect them."
The Latics had gone six Barclays Premier League games without a victory before their 2-1 win against West Ham last weekend, but they performed superbly They passed with finesse, looked dangerous on the counter-attack, and Arouna Kone made life difficult for Steven Caulker and William Gallas throughout.
"Many people watching will say Spurs had a bad day, but I wouldn't agree with that at all," Martinez said.
"We had to work very hard today. We were brave, we stopped Spurs from playing and we played high up. That opened up space for players like Gareth Bale and Aaron Lennon but the concentration and partnerships all over the park helped us to stop Spurs from having a say on the ball."
