Premier League champions: 2009/10
Our fourth league championship came after a wait of four years, a short period compared to the 50 it took for our second to arrive in 2005, but no less of a relief after three seasons of Manchester United success.
The first game of the campaign gave an early clue of how things would pan out, Didier Drogba opening the scoring before we were pegged back, only for the Ivorian to rescue Carlo Ancelotti's first league game in charge with an injury-time winner from a near-impossible angle.
Victory at Sunderland incorporating an unfamiliar 4-4-2 diamond formation followed, and we were still on maximum points after six games, Spurs, the surprise package of the season, despatched 4-0 at Stamford Bridge.
Our first defeat came at Wigan, where we were eventually reduced to nine men, and was followed up with another at Aston Villa but we bounced back with five straight wins, including a tight 1-0 against Man United and a 3-0 pummelling of Arsenal on their own ground before another defeat at Manchester City.
Going into the New Year, the Blues were well in the race for the title, and smashed Sunderland for seven to prove it. John Terry rose highest to head a late winner at Burnley to leave us top by a point at the end of January.
Victory over Arsenal was the highlight of an indifferent February which saw us beaten 4-2 at home by Man City, but we recovered to end March by hammering Portsmouth and Aston Villa with an aggregate score of 12-1.
Man United were a point ahead as we prepared to go to Old Trafford, where a Joe Cole flick put us in front only for the hosts to equalise. Substitute Drogba stepped forward though and smashed home a winning goal to put us two points clear, a lead we would not surrender despite defeat at Spurs in mid-April.
We ended the campaign in style, winning three out of three. Salomon Kalou snaffled a hat-trick against Stoke in a 7-0 gubbing before sweet, sweet victory at Anfield put the title within reach. The last obstacle was Wigan at the Bridge, and we needn't have worried.
Nicolas Anelka put us in front on five minutes, and it was two before half-time thanks to a Frank Lampard penalty - his 27th goal of the season. Kalou and Anelka added more before Drogba chipped in with a hat-trick to claim the Premier League Golden Boot, and Ashley Cole rounded things off to make it 8-0 in injury time.
The title had been won in style, with a record 103 goals scored in the 38-game campaign, and a share of the Golden Gloves for Petr Cech, who had kept 17 clean sheets.
