Books in the Luca Caioli series

Mario Balotelli has a reputation like no other in football. Since exploding on to the scene at Inter Milan in 2007, he has won league titles in both Italy and England, moving between Europe's elite clubs. Yet for all his undoubted talent, he is better known for his off-field antics - not least his infamous run-ins with both the police and Manchester's firefighters. Once described by Jos Mourinho as 'unmanageable', match-winning performances at the highest level have continued to convince clubs such as AC Milan and Liverpool to give him a chance. With exclusive access to friends, teammates and coaches, acclaimed football biographer Luca Caioli talks to the people best placed to explain the mystery that is Mario Balotelli.

On 1 September 2015, Anthony Martial completed his transfer from Monaco to Manchester United. At just 19 years of age, the fee of GBP36m (potentially rising to GBP58m) made the France international the most expensive teenager of all time. Eyebrows were raised at the landmark fee but a goal against Liverpool in his first game helped get the supporters onside, while a number of key strikes in his debut season soon won over the critics as he became integral to Manchester United's attack. Renowned sports biographers Luca Caioli and Cyril Collot talk to coaches, teammates and even Martial himself, to provide an unrivalled behind-the-scenes look at the life of the teenage superstar.
