#2 Ryan Sessegnon
With Pochettino's impressive record at developing youth, Sessegnon could be a smart long term investment. The young versatile English man can play superbly down the left flank. Such versatility could be of huge benefit to Spurs, who often seem to burn out in the later stages of the season.
Despite his tender age and an up and down season for relegated Fulham, Sessegnon is already putting up similar numbers to Tottenham's current established left-back, Danny Rose. The Fulham player completed 0.9 key passes, similar to Rose's 1 key pass every match in the Premier League. Sessegnon also produced 6 assists, double of Rose's 3.
While Sessegnon may be doing well on the offensive end, he undoubtedly needs to work on the defensive side of his game. But at just 19, Sessegnon has plenty of time to work on this. After Fulham's relegation from the Premier League, Sessegnon would reportedly cost around £30 million.
