REAL MADRID

Real Madrid-Celta Live

Real Madrid are set to pay 10 million euros for the signing of AIK Solna starlet Alexander Isak, according to Swedish newspaper Aftonbladet.

Madrid are expected to complete the signing of the 17-year-old striker, who is considered one of Europe's most exciting prospects, this week.

Isak agents expected in Madrid this week to seal deal

Isak is represented by the brothers Vlado and Zoran Lemic, whose clients also include present Real midfielder Luka Modric (a factor that has helped the deal).

It's understood that the two agents are scheduled to fly to the Spanish capital on Wednesday to thrash out the final terms of the transfer with Los Blancos.

Biggest ever transfer in Swedish football

If Real do spend 10m on Isak, it will be the biggest ever fee involving a Swedish club - ahead of the 7.8m Ajax paid Malmö for Zlatan Ibrahimovic in 2001.

Los Merengues' one-window FIFA transfer ban means they cannot register any new players this January, but does not prevent them from making signings.

Madrid's plan is therefore for Isak (who became Sweden's youngest ever scorer last week) to arrive in the summer - when they will be able to register him - at which point he'll join the squad of 'B' team Real Madrid Castilla.

Invited by Real to win over Sporting in November

Real have been tracking Isak for some time, with the youngster - born in Stockholm to Eritrean parents - visiting the club's facilities in November last year.

He was also a guest of the current Champions League holders at their 2-1 home LaLiga victory over Sporting Gijón at the Santiago Bernabéu.
