Atletico Madrid have been assured they've made a super signing in Matías Kranevitter.

Sporting CP striker Teófilo Gutiérrez played with Kranevitter at River Plate.

“He's going to be among the top 5 players in the world.

“There's always the possibility; at some point in the future returning to River would be amazing," Gutiérrez told La Red.

"I wish them all the best and hope they can win it."
