Alan Shearer: This Chelsea star was the secret to their success against Man City

That’s according to pundit Alan Shearer.
Antonio Conte’s men remained at the summit of the
Premier League table after their 3-1 victory against
Manchester City yesterday.
Costa - who netted his 11th league goal of the
season - was on target once again at the Etihad.
Eden Hazard and Willian
also scored to sink Pep
Guardiola’s side and send
a warning message to
their Premier League
rivals.
And Shearer has hailed
Chelsea’s star striker,
claiming he’s back to his best.
“He [Costa] was pivotal to Chelsea’s success,”
Shearer told Match of the Day.
