#2 Dele Alli

The Englishman might not be having his greatest season—or even as good a season as he had last term—but he is still among the most sought-after youngsters in the Premier League. The former Dons player is known for his ability to score crucial goals—especially in games where he is seemingly passive and not contributing much—and win games for his team.
This season, however, has been a far cry from what he could actually do—and his current wages must have something to do with it.
Alli is currently on a meagre £50,000-a-week. For someone who scored 22 goals from midfield—many of which were crucial ones—he is certainly getting less, especially when compared with players of similar calibre as the 21-year-old.
He only signed a contract last year, so it would be difficult to see him sign another in the foreseeable future, but if Spurs are to keep hold of him, they must give him what he deserves.
