"Manchester United" goalkeeper David De Gea says that the new World Cup ball will cause serious problems for players in his position.
The 27-year-old player noticed this in a friendly match between Spain and Germany, where he allowed a goal by Thomas Muller.
In the most important national team tournament happening in Russia, elite teams will play with the "Adidas" made ball "Telstar 18".
"It's really strange," De Gea said. "It could have been made much better"
His teammate Pepe Reina agreed.
"I bet that we will see at least 35 long-range goals in Russia, because it's impossible to understand it," said the "Napoli" goalkeeper.
"It's covered with a plastic film, which makes it difficult to control. Goalkeepers will have a lot of problems with this ball."
