Watford have reportedly targeted signing Chelsea defender Nathan Ake permanently as one of their top priorities this summer.

The Dutch Under-21 international has become first-choice left-back under Quique Flores this term, making 20 appearances and scoring one goal in the Premier League.

According to The Mirror, the Hornets are also interested in another season-long loan move in 2016-17 should they fail to agree a full-time switch with Chelsea.

Ake signed a five-year contract extension at Stamford Bridge last summer before heading to Watford on loan.
