Tottenham defender Ben Davies believes the manner of his side's defeat at Watford was inexcusable.

Spurs crashed back down to earth after Monday's impressive win over Manchester United as they fell to a 2-1 defeat at Vicarage Road to lose their 100 per cent start to the season.

They were well below their best, but still went ahead thanks to an Abdoulaye Doucoure own goal only to blow it as headers from Troy Deeney and Craig Cathcart in the space of seven minutes handed Watford a first-ever Premier League win over Tottenham.

Davies said: "It's disappointing, especially conceding from two set-pieces.

"We had a great start and it felt like it was undone by two sloppy goals.

"We weren't at our best but when you go ahead you want to see out the game and we're disappointed not to do that.

"It's very disappointing. We didn't really get cut apart by extremely good football.

"If that happens sometimes you can accept it. But two set-pieces, it was sloppy and we're very disappointed."

"We have to learn quick. We have to get it out of our system and make sure that we work on it ready for the next game."
