Striker Alvaro Morata appears to be targeting a swift return for Chelsea after a hamstring injury ruled him out of international duty with Spain.
The 24-year-old was substituted after 35 minutes of Chelsea's 1-0 loss to Manchester City in the Premier League last Saturday with the injury to his left hamstring.
He was ruled out of Spain's World Cup qualifiers with Albania and Israel after an MRI scan showed "a grade II myofascial injury in the hamstring muscles", the Spanish Football Federation said.
Such an injury could result in a month-long absence, but Chelsea will make their own assessment when the 24-year-old returns to London later this week.
