As the transfer deadline approaches, Tottenham may be in danger of having to make a panic defensive midfield purchase.
As rumours continue that Tottenham remain in the market for three positions: up front, on the wing and in defensive midfield, the Londoners have a responsibility to bring in a players that leave them stronger than they were last season.
Of course all those positions arguably need strengthening, with many thinking the club should have made attacking additions over the last few seasons, but considering the players sold over the last 12 months or so, the transfer committee at White Hart Lane have a particular responsibility to bring in a certain level of player in the middle of the park.
Eric Dier is currently doing well in defensive midfield, but it is a big expectation for him to not have his struggles there at some point this year considering he's a trained defender, while if the England Under-21 man was to suffer an injury there is no natural back-up.
Links to the likes Victor Wanyama, via the Mirror, are encouraging, however difficult it may be to convince Southampton to sell another one of their stars, but Spurs need to make sure the defensive midfielder they sign is an upgrade on those they have sold over the last year, with a whole host of players that played centrally being allowed to leave the club.
Fan favourite Sandro was one of the first to be stricken from the squad upon Pochettino's arrival, after Jake Livermore completed a permanent move to Hull in June 2014. This summer has seen three more central midfielders who have experience of playing defensively sold on, with Paulinho, Etienne Capoue and then Benjamin Stambouli all departing.
For many, that should mean the club make a big outlay on someone who has proven quality in a top division, or at a top club that has taken part in European competition. Even better than that would be someone who has shone in the Premier League.
Of course, though Pochettino may have decided the players he sold didn't fit into his dynamic, pressing system, or just clashed with them on a personal level, what would be a giant waste of time would be Spurs signing another stop-gap central midfielder who in reality, is unlikely to match the form of a fit Sandro, even if the club would have had to wait for that, or the obvious solid if unspectacular ability of Capoue or Stambouli.
Otherwise the shelf life of defensive midfielders at Tottenham is going to continue to be between one and two years.
