Kevin Mabu

Newcastle defender Kevin Mbabu is to return to his native Switzerland to spend the season on loan at BSC Young Boys.

The 21-year-old full-back, who signed a two-year contract extension earlier this summer, made his Premier League debut in a 2-2 draw with Chelsea in September last year.

Mbabu, who joined the Magpies from Servette in January 2013, has five senior appearances to his name.
