Porto exercise purchase option on Oliver Torres

Atletico Madrid midfielder Oliver Torres is currently on loan at Porto, but the Portuguese side have now exercised their right to buy the 22-year-old.

When the Spaniard joined Porto, a buy-out option of 20 million euros was included in the initial loan and this will be effective from the end of the 2016/17 season.

Former Real Madrid captain Iker Casillas plays for dragons and Torres has become a regular in the starting line-up along with his compatriot, Ivan Marcano.

The move comes after a successful loan spell in Portugal during the 2014/15 campaign, but Torres was unable to break into Diego Simeone's side during his time back in Madrid.

As part of the original deal, Diego Jota was loaned from Porto to Atletico.
