Joao Felix has shared his initial impression of when he first met Juventus forward and Portuguese legend Cristiano Ronaldo.
The Atletico Madrid youngster saw the former Real Madrid superstar before a game with the Portuguese national team.
"I was used to watch him on TV," Joao Felix told Eleven Sports.
"[When I met him] he looked like he was three metres tall."
The 20-year-old went on to stress that Liverpool, who will face Atletico in the last 16 of the Champions League, are the toughest team his side could face in the tournament.
"Liverpool are in a very good shape," Joao Felix noted.
"They are the [Champions League] holders and it will be very difficult, like any match in the Champions League.
"But against Liverpool, who are doing great, it will be even more difficult.
"[Liverpool] are the toughest opponent of all."
