The Spanish giants have been quiet in the transfer market, with the club re-signing Spanish striker Alvaro Morata from Juventus while selling Jese Rodriguez and Denis Cheryshev to Paris Saint-Germain and Villarreal.
Perez, whose side beat Sevilla 3-2 in extra-time on Tuesday to lift its third UEFA Super Cup, said on the club’s official website: “Up until 31 August anything can happen, but we’re really satisfied with the players that we’ve got.
Real’s priority is to strengthen their midfield line for the 2016-17 campaign.
However, the Champions League winners, lost out on signing French midfielder Paul Pogba, who re-joined Manchester United from Italian champions Juventus earlier this week on a reported world record fee of £89m.
Italian midfielder Marco Verratti, who was also a target of Real, extended his contract with Paris Saint-Germain until June 2021 last week.
