Chelsea eased to a 5-1 victory over Leeds United at Elland Road to seal their progression to the Capital One Cup semi-finals – but it took a first half scare to put them on track.
It was believed that some of the Blues stars could struggle due to their travails and travels as they attempted to win the Club World Cup in Japan.
Leeds, though, took full advantage of their lethargic opponents as Luciano Becchio slid home Jerome Thomas’ cross from the left after 37 minutes, sending the crowd wild at a packed Elland Road.
And they nearly doubled their lead moments before half time as Tom Lees headed over, while Jamie Ashdown had to be on form to keep out Lampard’s thunderous free-kick in added time.
Just seconds after the restart Chelsea were level though as Mata’s weak shot squirmed beyond Ashdown to give him his fifth goal in five games.
The ex-Portsmouth goalkeeper redeemed himself though as he kept Fernando Torres and then Lampard at bay.
There wasn’t much he could do after 64 minutes as Branislav Ivanovic powered home a header from Lampard’s corner to make it 2-1.
And almost immediately from the kick off Rafa Benitez’s men made it 3-1.
Victor Moses picked up the ball 40-yards out, drifted in from the left and then thrashed an effort in at the luckless Ashdown’s near post.
Chelsea were now dominant as Leeds capitulated in the rain on home soil and goals from substitute Eden Hazard and Torres late on boosted the scoreline to 5-1.
