Weâ€™ve seen some mad goalkeeping drills through the years, and this is another one.
Keylor Navas, Costa Ricaâ€™s superb 27-year-old goalie, has become a massive name at the World Cup in Brazil, and now new footage has come to light showing how the stopper sharpens his skills.
Filmed at Levante, whom he plays club football with, Navas is filmed in a drill facing off against tennis starÂ Pablo Andujar.
In short,Â Navasâ€™ job is to try and stopÂ Andujar from forehanding tennis balls into his net at a speed of aroundÂ 160 km/h.
