Chelsea might only be fourth in the Premier League table, but the Blues have the best combination in Cesar Azpilicueta to Alvaro Morata.
The Spanish duo have formed a good understanding which has seen Azpilicueta assist Morata five times in the league already.
Former Chelsea striker Tony Cascarino has revealed the impact their understanding can have for Chelsea.
Cascarino told The Times: “Cesar Azpilicueta has created five goals for Alvaro Morata, the best figures in the top flight this season.
“I’ve played in sides where I’ve had a great understanding with one player and it makes a huge difference.
“You’re more likely to gamble on getting into a scoring position because you know he will find you.
“Strikers who have had a sustained period of success will say it is because of the supply line, the person who has an understanding with them.”
