2. Saido Janko
The Swiss U19 international was signed recently by United and then loaned to Bolton Wanderers in 2015. The 19-year-old can play anywhere on the right side of the team but is most comfortable playing as a right back. Janko does have really good pace and has strength to survive in the Premier League, he could be playing a bigger role next season as the likes of Rafael or Valencia could have their game time scuppered by the youngster.
