Bruma is a talented Dutch central defender who will return to Hamburg for a second consecutive season on loan in the Bundesliga.

The left-sided player has been out on loan five times already with spells at Coventry, Newcastle, Leicester, Wigan and Vitesse. It appears that the Dutchman's career has stalled and that a permanent move away from the Blues would be for the best.
The Uruguayan spent last season on loan at Defensor Sporting, where he scored once in two games. Only 19 years old, another loan spell beckons, probably in Uruguay again.
The Czech defender has enjoyed loan spells with Sigma Olomouc, who originally sold the player to Chelsea for £5 million in 2010. Last season at Vitesse proved to be a fruitful period with 29 league appearances, and the 19-year-old would benefit from another season in the Eredivisie.
A young Mexican sensation who joined the Blues from Guadalajara in 2011, he was sent on loan to Vitesse also, but Dávila only made two appearances all season. The 21-year-old will hope for a better loan spell this season.
A talented forward who is versatile across all the positions in a front three, the 19-year-old was another player sent to the Eredivisie, with ADO Den Haag. Lalkovič only made two appearances, but his future looks promising given that he is already featuring heavily for the Slovakia under-21 side.
Chalobah was part of the England under-17 side that featured at the FIFA under-17 World Cup in Mexico in 2011. Apt in midfield as well as defence, with a classy touch and presence on the ball, he's a real star in the making. He's currently featuring for the England under-19 side.
