In Rafa Benitez, Newcastle United can boast of once having one of the best managers to ever grace the English Premier League. The Spaniard won the La Liga with Valencia, the Champions League with Liverpool, the English Championship with them and also managed the likes of Real Madrid, Napoli, Inter Milan, and Chelsea. Benitez is currently with Chinese Super League outfit Dalian Yifang, but hasn’t ruled out a return to Europe. Having seen some of his former players become managers, the former Magpies boss believes five Newcastle players have what it takes to go into management after retiring.
