Bilbao's Kepa could replace Courtois

Courtois missed training on Tuesday for the second day in a row, all but confirming reports that he will join Real Madrid before the end of the transfer window. 

Chelsea have reportedly enquired about bringing Stoke City and England goalkeeper Jack Butland to Stamford Bridge, and have also been linked with Atlético Madrid's Jan Oblak. Chelsea could trigger Oblak's release clause of £89m, but Jack Butland allegedly remains their first choice to replace Courtois. 

Kepa, 23, signed a new seven-year contract with 'Los Leones' in January 2018 amid speculation linking him with a move to Real Madrid. Thus, Chelsea would have to break the player's release clause, which stands at a staggering £70m. 

However, the Spain international turned up to training as normal on Tuesday afternoon in preparation for the new season. 

Athletic begin their campaign at home to Leganes on Monday 20th August.
