The pressure on under-fire Tottenham manager Ange Postecoglou increased following Sunday's dire 2-1 defeat against relegation-threatened Leicester City.

Some fans called for Postecoglou to be sacked after they were beaten by the Foxes at the Tottenham Hotspur Stadium. Richarlison gave Spurs the lead in the first half and it all looked comfortable for the home side, up until Leicester turned it around after the break thanks to goals from Jamie Vardy and Bilal El Khannouss.

Audible boos were present during the second half and after the final whistle as Tottenham supporters made their feelings clear. Most were directed at chairman Daniel Levy due to their lack of spending power, while others were at the team - and Postecoglou - after suffering their fourth straight Premier League defeat.

It's a result that leaves Spurs down in 15th on just 24 points from their 23 top-flight matches. Despite that, football.london understands that Tottenham are sticking with Postecoglou, and don't intend to sack him.

While Tottenham's form has been dreadful of late, Postecoglou can be defended by the fact they are enduring a horrendous injury crisis right now, with 10 players missing the Leicester defeat.

Guglielmo Vicario, Micky van de Ven, Cristian Romero, Destiny Udogie, James Maddison, Djed Spence, Brennan Johnson, Wilson Odobert, Timo Werner and Dominic Solanke were unavailable. Richarlison and Pape Matar Sarr, meanwhile, also appeared to pick up injuries against the Foxes, adding to their worries.

And it's understood that Spurs will try and sign at least one player for Postecoglou in the days ahead to ease the pressure on his depleted squad, even if that might have happened earlier in the window.

Tottenham have made one signing so far this month. Antonin Kinsky arrived from Slavia Prague for £12.5million earlier in the window due to Vicario suffering a broken ankle and the Czech Republic goalkeeper has impressed since arriving, keeping two clean sheets in five appearances across all competitions.

However, with Levy and the Spurs board willing to sign at least one more player before the end of the January window, which position are they going to strengthen. There is an argument to suggest that Tottenham need to add in a number of areas, including centre-back, left-back and on the right-hand flank.

A new centre forward could be a position that is targeted, as well. With Richarlison limping off with a groin injury against Leicester and Solanke out for, at least, five more weeks, Spurs might need to dip into the market and add another No.9. Signing someone on loan does seem the most suitable idea right now.

Will Lankshear has risen to prominence after impressing in the club's academy and he's an option to play up front, but Spurs might need someone with more experience to help them get out this mess. Scoring goals hasn't been a main issue this season but, without a senior striker available, it could soon become a problem.
