The one concern that emerges from Mitchell's appointment at Spurs

Tottenham Warm Up

Tottenham Hotspur's appointment of Paul Mitchell is no guarantee for success in the transfer window.

The signing of Paul Mitchell at Tottenham Hotspur may be the most important that the club have made in many years. 

The former Southampton talent scout has been widely credited with bringing in an influx of lesser known stars to St. Mary's in recent times.

Mitchell was reportedly the mastermind behind the transfers of Sadio Mane, Dusan Tadic and Graziano Pelle at Southampton and the hope is he can be similarly successful in North London.

Spurs's record in recent transfer windows has been awful with most of their money being squandered on players who have failed to impress.

While Hugo Lloris and Christian Eriksen stand-out as the best buys the Lilywhites have made, there are a number of players who appear to have cost Tottenham a lot of money for very little return. 

Roberto Soldado, Paulinho and Vlad Chiriches all look set to become major flops at White Hart Lane and there are still doubts over a lot more of their recent recruits. 

Mitchell will be aiming to install a more productive strategy at the club, as they look to add masses of quality to their squad in January, and the transfer windows beyond that.

Mauricio Pochettino's options in his first-team squad are currently limited and an overhaul is needed at Spurs to get them back on the right track.

Mitchell's appointment, though, cannot be considered a guarantee for success. 

There is no doubt he did a good job with the Saints, but his transfer policy was backed up by a successful youth-team. 

Southampton produced the likes of Calum Chambers, Adam Lallana, Luke Shaw and James Ward-Prowse to supplement the quality additions that Mitchell was bringing in and this is an area that Spurs need to improve in.

Pochettino has said that he will trust his youth-players far more and has already proven true to his word - with Ryan Mason's emergence a highlight of his regime so far. 

It would also be wrong to analysis Mitchell's recruitment as a total success at Southampton. 

Although there were a number of good additions, for every Pelle there was an Emmanuel Mayuka and for every Tadic there was a Gaston Ramirez. 

Mitchell also brought in Vegard Forren, who made a swift exit and is now back at Molde, Paulo Gazzaniga and Saphir Taider during his time on the South Coast.

It shows that although it is a positive move from Spurs it is not a guarantee of success and it will take more than Mitchell's arrival to make their transfer strategy fully effective.
