Two years ago, AC Milan sold Kevin-Prince Boateng to German club Schalke. It was a move that was a long time coming.
The midfielder had been at the San Siro for three years and had developed into an enigma. He had huge highs, like the October day in 2011 when he came on as a substitute and scored the second-fastest hat trick in Serie A history—14 minutes to David Trezeguet's 10 in 2001—to turn a 3-0 deficit into a 4-3 win over Lecce.
But he also had some lows. He was prone to sulking and sometimes looked out of place transitioning from a more box-to-box midfielder to a trequartista.
