Rovers were holding their own against a much improved Chelsea team, but fell behind early in the second half when a corner from Florent Malouda was flicked on by John Terry and Ivanovic was on hand to fire his shot through a wall of bodies and into the net.
The Serbian defender also had a hand in Chelsea’s second 15 minutes from time when his goalbound header was flicked in by Anelka from close range.
Chelsea were good value for their win as the Blues ran out comfortable winners.
Blackburn sit in 11th place tonight in the league.
