5. Derlis Gonzalez - Basel / Paraguay

One of the most promising youngsters on this list, Derlis Gonzalez is just 21 years of age, yet has proven himself as a natural goalscorer against the most impressive of back lines. The Paraguayan scored three Champions League goals for FC Basel this season, notching against Real Madrid, Ludogorets Razgrad and Porto. His diminutive stature could be a drawback, especially in the notoriously physical Premier League. His versatility fits in with Sunderland's needs however, capable of playing as both a striker and winger.
