Juan Mata played a decisive role in our upturn in fortunes in the second period, setting up John Terry's equaliser with a set-piece. He also completed more successful passes than any other Chelsea player while on the pitch, with 85% finding a man in blue.
Exactly half of Mata's 20 passes were in the final third, but he also played his part defensively, making seven ball recoveries - again more than any of his team-mates - including four in his own half. The 25-year-old attempted three tackles after his introduction; only Ramires and Frank Lampard made more.
Jose Mourinho's men completed 16 successful clearances in the opening 45 minutes, but just four after that until the sending-off of Fernando Torres in the 81st-minute, hinting at our dominance in the second-half when it was still 11 against 11.
