Tottenham's biggest players have gone missing and Ange Postecoglou has NO plan B

At the start of the season everything appeared to be on the right track for Tottenham, with the newly-appointed Ange Postecoglou guiding his side to eight victories in ten games as they enjoyed an unbeaten start to the Premier League campaign.

There was talk that Tottenham could win their first league title since 1961, but such discussions are now a distant memory, with Postecoglou's team currently in the midst of a miserable run of form as the season nears its conclusion.

Although it is still mathematically possible, securing Champions League qualification looks as if it will be a tall order for Tottenham, who have lost their last three games including defeats against rivals Arsenal and Chelsea.

The belief appears to have sapped away from Tottenham in recent games and Postecoglou will be eager to ensure that the problems don't run into next season.

Mail Sport assesses why Tottenham have struggled of late.

Struggles from set-pieces

Defending set-pieces has proven to be a major problem for Postecoglou's team, especially since December, and they have conceded 22 goals from such situations in the Premier League this season.

Postecoglou has claimed that he isn't especially bothered by the issue, saying: 'I'm not interested. Never have been. Not in the least.

'It's not the first time I've been questioned about set-pieces in my coaching career. There is an underlying reason for that which I'm very, very comfortable with.'

Tottenham were again vulnerable from set-pieces in their 2-0 defeat to Chelsea and there is little sign of the situation improving any time soon.
