Alvaro Morata is primed to lead Chelsea's attack against AS Roma in the Champions League on Wednesday as the Blues seek to quickly erase the embarrassment of their weekend loss to the Premier League's bottom club Crystal Palace.

The Spaniard missed the 2-1 defeat after injuring his hamstring against Manchester City before the international break.

But the £58 million striker underwent full training on Sunday and Chelsea captain Gary Cahill indicated his return is imminent.

"He is back out on the pitch and hopefully he keeps progressing okay," said Cahill.

That will be welcome news to Chelsea manager Antonio Conte who substituted Morata's replacement Michy Batshuayi on Saturday after 57 minutes of his second league start of the season.

A nine-point gap separates Chelsea from leaders City but the Blues top their Champions League group, two points ahead of second-placed Roma, after winning both opening Group C games.

One of Morata's seven goals this season came in Chelsea's 2-1 victory at Atletico Madrid, a result and performance that suggested the London club could be a real force in the competition.
