Despite Chelsea's confidence in Courtois renewing his contract at Stamford Bridge, the London side are still keeping a few other options up their sleeve that could come into play if the Belgain head off to the Bernabeu.
According to the 'Mirror', Chelsea are closely following Roma's goalkeeper Alisson who is also on Madrid and Liverpool's shopping list.
The 25 year old shotstopper is also on the cusp of renewing his contract at Roma which would inflate his price tag to €80 million. Chelsea, however, are aware they'll have to pull out all the stops for a top quality keeper should Courtois bid farewell to London.
