Rafa Benitez has confirmed that the pair will miss Chelsea’s Europa League second-leg clash against the Czech side, with the Spanish boss opting to rotate his weary squad
The European champions have a one-goal advantage courtesy of Oscar’s late strike in Prague, so Benitez will take the opportunity to rest some of his more weary players.
The Blues’ 33-year-old midfielder has appeared in all 13 of Chelsea’s matches in 2013, starting 11 times, while Ivanovic has missed just one encounter since the turn of the year.
"Frank has been playing a lot of games," Benitez said in his pre-match press conference. "Managing the squad means we can keep fresh legs on the pitch."
John Obi Mikel’s involvement in the Africa Cup of Nations and injury to David Luiz forced Lampard to play a number of games in quick succession, but their return allows the veteran midfielder a much-needed break.
But, three goals shy of Bobby Tambling’s all-time goalscoring record, the decision to rest Lampard means he can set his sight on Sunday's clash with Manchester City as another chance to eclipse the milestone, though his manager has backed him to do so.
"It would be fantastic for him, and fantastic for us if he breaks the record," continued Benitez.
Despite rotating his squad and already having a first-leg lead, Chelsea's interim boss is wary of the threat Sparta Prague pose, and refuses to take their threat lightly.
"We know tomorrow will not be an easy game, they are a good side," the Spaniard added. "Winning three games in a row is good for confidence but it's also good that competition for places is very high."
