Real Madrid are assessing whether to make a surprise summer move for Kristoffer Ajer following his impressive showings in the Scottish Premiership this term.
The Celtic star has been an integral part of a defence which has just helped the club win its ninth top-flight crown in succession.
But his impressive form is now attracting attention from outside of Scotland, with Madrid among the teams monitoring the player, according to Mundo Deportivo.
The Spanish giants however could face a tough battle for the 22-year-old's signature with Paris Saint-Germain, Manchester City and Leicester City also showing interest.
