As per Daily Star, Pochettino has asked the club to sign the 25-year-old this summer.
It is no surprise that Spurs need to improve their attacking unit and Diaz could prove to be a quality addition.
Currently, Spurs are reliant on Harry Kane for goals and Diaz could be the ideal backup for him. Also, he could partner Kane in the attack depending on the opposition.
Tottenham need a quality back up for Kane and it will be interesting to see if they can get the Diaz deal over the line.
Real Madrid are unlikely to offer the player regular game time next season and a move away from Santiago Bernabeu would be the best for him.
