Tottenham need midfielders - should they look at Charles Aranguiz?
Whilst defenders Kieran Trippier, Kevin Wimmer and Toby Alderweireld have all arrived, the Spurs boss has also overseen the exits of midfielders Etienne Capoue and Paulinho, who have joined Watford and Guangzhou Evergrande respectively.
Pochettino has nurtured the likes of Nabil Bentaleb and Ryan Mason, but with Benjamin Stambouli set to join Watford according to the Watford Observer, Pochettino will find himself short of options in midfield.
Bentaleb, Mason, Mousa Dembele and youngster Dele Alli is far from strong enough for Spurs if they bid to reach the top four next season, meaning Tottenham should be in the market for at least one more midfield player. Pochettino will no doubt have a list of targets in mind, and Chile international Charles Aranguiz - a target for Arsenal according to the Daily Mail - should be under consideration.
Aranguiz, 26, was in exceptional form for his country as Chile won Copa America earlier this summer, providing drive in midfield and creativity in the final third.
Currently playing for Brazilian side Internacional, Aranguiz has been seen as one of the most underrated midfielders in world football over the last few years, mostly down to his consistently brilliant performances in the Chile midfield alongside Arturo Vidal.
Aranguiz could strike up a formidable partnership with Bentaleb in the Tottenham midfield, though more emphasis would be placed on the latter to break play up given Aranguiz's lack of real physicality.
Both players have impressive passing ranges and technical ability, whilst Aranguiz has the energy that made Ryan Mason so successful last season - but he also possesses an impressive goalscoring record, which would give Tottenham another dimension in midfield that Mason, so far, hasn't provided.
Factor in how Aranguiz featured on the international stage under former Chile boss Marcelo Bielsa - the man widely credited with forming the basis of Pochettino's tactics - and the 26-year-old could be an ideal fit for Pochettino's Tottenham side.
A move to Europe seems somewhat inevitable at some point in the near future, and with interest growing from English clubs, Tottenham should be looking to lure him to White Hart Lane this summer.
