Despite the spending among their top-six rivals, Spurs chairman Daniel Levy said on Thursday that it is "difficult" to do business in January - a message repeated by Pochettino ahead of Saturday's match against Everton.
Tottenham have allowed out-of-favour winger Georges-Kevin Nkoudou to join Burnley on loan until the end of the season but have yet to bring in any additions in January.
As much as it sells itself as the biggest and most exciting league in the world, the Premier League has still to find a way to keep its biggest stars from the clutches of La Liga's superpowers.
Harry Winks (ankle) and Toby Alderweireld (hamstring) are also absent, but Pochettino has a fully fit squad to choose from otherwise. Jordan Pickford will likely start in goal, with Jonjoe Kenny, Phil Jagielka and Cuco Martina all starting in defence and Ashley Williams may replace Mason Holgate in the center of defence.
'I don't see Harry Kane leaving Spurs,' says Harry Redknapp
While there had been a feeling that the young player may explore other options amid glowing praise, he is content with both his development at Spurs and the development of the team. Harry Kane has netted eight goals in that five game period. With 12 goals from his last 11 games, the striker continues to plough his way through opposing defences.
New Everton signing Cenk Tosun is set for his debut after completing a move from Besiktas and Allardyce has confirmed he's itching to feature.
There has been an impressive roster of players to have fallen from Tottenham's academy conveyor belt in recent years. Real's interest in Kane has seen Levy's guard go up. Richards is still a long way from playing at that level, never mind proving to be a success. The 30-year-old has made 18 appearances this season and has been a regular in the first team under Sam Allardyce.
Spurs will kick-off at home to Everton at 5.30pm on Saturday and will know how third-placed Chelsea have got on at home to Leicester City at Stamford Bridge.
