This summer’s GAMBLE signings: Chelsea, Liverpool, Manchester United and City newcomers among riskiest transfers

4. Aleksandar Mitrovic – Newcastle United

Described as a ‘a five-year-old trapped in a monster’s body’, Mitrovic has a reputation as an unpredictable hothead, which has already been established in just three games for Steve McClaren’s side. The 20-year-old has racked up two yellow cards and one red card in as many appearances for the Toon, and could be a huge risk every time he steps out onto the pitch.
