THE DATA DAY: TOTTENHAM v CHELSEA

It was the proverbial game of two halves on Saturday as we fought back from a goal down to secure a well-earned point at White Hart Lane. Both managers praised the performance of Juan Mata after his introduction at the interval, and the key figures suggest that the Spaniard's influence was not limited to creative duties…

After a disappointing opening period, the second-half saw Chelsea create more chances, attempt more shots on goal, and make more successful passes in the final third.

We also made more ball recoveries, more tackles and more blocks after the break.

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.

After the dismissal we were forced onto the back foot, making just 21 successful passes to Tottenham's 96. Forty-eight of those passes by Spurs were in the attacking third, more than their total number up to that point in the match. Five of the 11 chances the home side created on Saturday also came after Torres had left the pitch.

We were caught offside on 10 occasions. Our previous five league games had seen us fall foul of the assistant referee's flag just eight times in total, suggesting that Tottenham afforded us more space than most have in behind their defence.

Much had been made before the game of Tottenham's impressive physicality, but it was the Blues who dominated in the air. We won 22 of the 28 aerial duels contested, with Branislav Ivanovic beating his man to the ball on all eight occasions he went up for a header.

Moussa Dembele was Tottenham's outstanding performer statistically, making and completing more passes than anyone else on the pitch, succeeding in all eight of his take-ons and tackling a Chelsea player four times, more than any of his team-mates. He also made two blocks, one more than four other players on both sides could manage.

Spurs have now won just three of their 43 Barclays Premier League games against us. Meanwhile Terry's well-placed header ensured that we didn't fail to score in three successive league games away from Stamford Bridge for the first time since April 2002.
