Tottenham completed the signing of Giovani Lo Celso from Real Betis on deadline day.
The Argentine midfielder has joined the Londoners on loan with an option to buy.
Lo Celso had a very good season in La Liga last year and it will be interesting to see how he adapts to the Premier League now.
The 23-year-old is an outstanding talent and he could be a key player for Spurs this season.
Pochettino needed the extra depth in attack and midfield and Lo Celso can cover multiple positions for him.
