Chelsea head coach Antonio Conte has revealed that Alvaro Morata has spent the international break ensuring that he is "100%" fit.
Morata struggled for form during the opening weeks of 2018, while the Spaniard has also been dealing with an ongoing back problem.
However, after not being selected for Spain's most recent fixtures, Morata worked on his fitness at the club's training ground and Conte has admitted that it has proven to be "very important" for the forward ahead of the remainder of the season.
At a press conference, the 48-year-old told reporters: "This period was very important for Alvaro. He has worked very well and he needed to work hard.
"He was out for one month and a half with his back problem. Now he is really fit, 100% and ready to have a final end to the season for Chelsea and then for him to have a chance for the World Cup."
Earlier this month, Morata ended a 13-match goalless streak by netting in the 2-1 win over Leicester City in the FA Cup quarter-finals.
