Morata is one of a quartet of Chelsea players who did not make the cut for Russia, alongside Marcos Alonso, Cesc Fabregas and Pedro. Cesar Azpilicueta is the Blues’ sole representative in the 23-man squad.
Morata has been a regular in coach Julen Lopetgeui’s setup over the last two years and led the line for La Roja at Euro 2016. However his struggles for Chelsea, with whom he has scored only three goals since the start of 2018, have cost him a spot on the plane to Russia.
Lopetegui said: “Taking important decisions is our job, we know that some will be tough but we will try as always to be correct and honest.”
In response Morata wished his team-mates "lots of luck in the World Cup! I will be supporting and encouraging [you] to the end as always!"
Manchester United goalkeeper David De Gea and David Silva of Manchester City round off the Premier League contingent.
