A sprint test between Cristiano Ronaldo and Gonzalo Higuain has surfaced online and the difference in intensity is staggering.
The Juventus squad were put through their paces in pre-season training with Ronaldo looking in supreme form.
He underwent numerous drills including a sprint test. He competed alongside fellow forward Gonzalo Higuain and the difference in speed and agility was very, very noticeable.
Higuain, whose returned to Turin following his loan spell at Chelsea, looked ponderous whereas Ronaldo flew out of the traps in blistering fashion.
Ronaldo scored 21 Serie A goals last season and ahead of the new campaign, Maurizio Sarri has challenged him to break Higuain's goal-scoring record for a single season.
The Argentine striker bagged an impressive 36 goals in Italy's top flight and Sarri, who managed Higuain during that term, is hoping to steer Ronaldo to more individual glory.
"I've trained great players over the years, but with Ronaldo I move on to the next level, a player who is at the top of the world," he said.
"This is a lad with every record in world football and I'd like to help him set another, knowing I contributed to it.
"I trained a player with the all-time Serie A record for goals in a single season.
"I'd like to make that two. It'd be an enormous satisfaction."
Higuain, meanwhile, remains subject to intense transfer speculation. He had been linked with a move to West Ham United with fresh reports claiming that AS Roma are interested in acquiring his services.
