Tottenham did not sign any senior players in January.
Merson said: “They had to let Andros Townsend go and they've got a settled team so I understand the lack of signings. It's been hard for them because the same team has played virtually every week and if you bring someone in and they don't play then you could look at it and think it's a waste of money - but they're a couple of injuries away from being blown away. I would probably have tried to get a world-class centre-half.”
Considering most fans wanted Spurs to sign a striker in January, Merson is surprising in that he would have tried to sign a world class centre-half.
Backup for Harry Kane seemed imperative if Spurs are to realistically win the title this season, but the Lilywhites opted to bring in no senior players throughout January.
The only signing made was Shilow Tracey, the young Ebbsfleet player who has linked up with Tottenham’s development squad.
There were many outgoings, with the most notable being Andros Townsend, Federico Fazio, Milos Veljkovic and Alex Pritchard.
Due to these exits, Spurs have left themselves slightly lacking in depth, and although Mauricio Pochettino has utilised a small squad this season, Merson believes the defensive positions could cost them success.
Jan Vertonghen is currently injured, meaning that Pochettino will be playing Toby Alderweireld and Kevin Wimmer at centre-back for the foreseeable future.
Eric Dier can also fill in as a centre-back, but Merson has suggested Spurs should have tried hard to sign a world class centre-back in January to improve their title credentials for the second half of the season.
