Chelsea: 5 Potential Replacements for Courtois 

#4 Jan Oblak

Jan Oblak replaced Courtois at Atletico Madrid

The Slovenian stopper was brought in as a replacement for the Belgian at Atletico Madrid in 2014, and has since gone on to become one of the best goalkeepers in the world, and would be the ideal replacement for Courtois.

Oblak earned himself mass plaudits for his impressive performances in La Liga and The Europa League last season, and he will come with a hefty price tag.

If Oblak were to leave Madrid for London, there is every chance that Chelsea could break Liverpool's recent £66.8 million transfer record for a goalkeeper in the process.
