Estonian goalkeeper Karl Hein, aged 23, impressed Real Madrid's president Florentino Perez with his performance in a 3-0 loss to Real Madrid in August. Perez noted that Hein had a good build and was a very capable goalkeeper. Nevertheless, Ronaldo pointed out to Perez that Hein was only on loan from Arsenal, indicating that any potential negotiations would need to involve the Premier League club. Hein, who had a breakout year at Valladolid last season, is in the final year of his contract with Arsenal and has drawn interest from Sevilla for another season in Spain's top league. Despite Real Madrid's interest, his future is still uncertain, as negotiations would necessitate Arsenal's participation. Transfermarkt lists the player's current market value at €3.00m.
