Chelsea will be hoping to get Atletico Madrid in Friday’s Champions League semi-final draw after it was revealed the two clubs’ loan agreement could prevent brilliant goalkeeper Thibaut Courtois playing in the game.

The news took the shine off one of the greatest nights in the club’s history after heroically toppling Barcelona and reaching the European Cup semi-finals for the first time in 40 years.

Atletico president Enrique Cerezo told Spanish radio Onda Cero that 'a large sum of money' would need to be paid by Atletico to Chelsea and that the club 'would be unable to pay'.

It is understood the clause was added in the loan agreement drawn up at the start of the season and could be as much as 3million Euros for each game. Atletico's financial situation makes them reliant on loans and third party investment and the 6m Euro fee would be beyond them.

If the clause is confirmed it would deprive Courtois of the biggest game of his career so far and Atletico of the keeper who has made them the toughest team to beat in the tournament this season.
