Gylfi Sigurdsson joined Spurs in July 2012  but has yet to fulfil his potential at White Hart Lane. New head coach Mauricio Pochettino may be the man to unlock the Icelandic midfielder's talent. 

Sigurdsson was signed on the back of a successful loan spell at Swansea City in 2012, where he scored seven goals and registered five assists in 19 appearances. The Icelander starred in the number 10 role under Brendan Rodgers and was tipped for big things.

However, since his move to North London, he has struggled to cement a place in the Spurs team and has spent the majority of his time at Tottenham in wide areas, mainly on the left-hand side.

Sigurdsson has been linked with an exit from the club and with Crystal Palace reportedly interested, it remains to be seen whether he will stay.

Pochettino, though, would be wise to keep Sigurdsson with Spurs in Europe next year.

The 24-year-old has scored only 13 goals in 82 appearances in a Spurs shirt but has not started most matches. 

At Southampton, Pochettino deployed Adam Lallana on the left-hand side of a midfield three, but the Englishman was allowed to roam inside and support the forward. The Argentine boss helped Lallana raise his goal ratio from the previous season to ten goals in 42 appearances.

Sigurdsson likes to come inside and shoot and in his preferred and most productive role as a number 10, he supports the striker. Pochettino could mould Sigurdsson into Spurs' - maybe better - version of Lallana.

Sigurdsson is tall, a team player, a dead-ball specialist, has an eye for goal and a great work rate off the ball. He has all the attributes to succeed in Pochettino's high-pressing and counter-attacking system employed at Southampton.

Pochettino can be the coach to coax the best out of Sigurdsson at Tottenham. The Icelandic international has all the qualities to fit into the Argentine's system used at Southampton and he could aid Spurs' charge for the Champions League next season and lift them up to another level.
