In many ways, football is a simple game: the team that scores the most goals, wins. Yet in every single match, there are intriguing statistical sub-plots that help make the beautiful game the fascinating spectacle that it is.

That's why, each week, takes a look at the numbers behind the results. This latest review reveals why the number 1,000 bore significance to Chelsea, 400 to Manchester United, and 100 to Frank Lampard, Emile Heskey and Xavi.

1,000 English Premier League goals is the figure Chelsea reached during their 5-0 defeat of Sunderland on Saturday. They became the fourth side to achieve the landmark, following Manchester United, Arsenal and most recently Liverpool, who did so thanks to a Fernando Torres strike one month ago today. It was a former Reds No9 who posted the Blues' milestone goal at the weekend: Nicolas Anelka, who scored their second en route to a personal hat-trick that took him joint-top of this season's scoring chart, alongside Wigan Athletic's Amr Zaki. Meantime, the Egyptian's strike partner and another ex Liverpool frontman, Emile Heskey, netted a last-gasp winner at Portsmouth for his 100th Premier League goal, while Chelsea's Frank Lampard recorded his ton in league matches: 99 in the Premier League and one on loan at Swansea City in the English third tier.

400 is the unparalleled number of Premier League victories belonging to Manchester United following their 4-3 win over Hull City at the weekend; all under the guidance of Sir Alex Ferguson, who assumed the reins 22 years ago tomorrow. The Red Devils consequently increased their cushion over second-placed Arsenal to 62, with Chelsea and Liverpool following on 318 and 314 wins respectively. United achieved their maiden Premier League success at the fourth time of asking on 24 August 1992, when Dion Dublin's solitary goal sunk Southampton. The reigning champions' latest success was indebted to two-goal Cristiano Ronaldo, who scored for the ninth home match running in the competition - a feat previously achieved only by Alan Shearer, who was on target in 16 successive games for Newcastle United at St James's Park between August 1996 and May 1997.

100 is the total of European club football appearances Xavi hit when coming on as a 60th-minute substitute for Barcelona at home to Basel, helping his team to a 1-1 draw that guaranteed their presence in the knockout phase with two matchdays remaining. The midfielder played his first game in Europe little over ten years ago, helping the Catalan giants share six goals with Manchester United at Old Trafford in the UEFA Champions League; a competition in which he has now appeared 86 times. Xavi became the first Barça player and fifth Spaniard to participate in a century of games on the continental club scene. He emulated a quartet of former Real Madrid representatives: Manuel Sanchis, Fernando Hierro, Raul and Fernando Morientes, who has also turned out in Europe for Zaragoza, Monaco, Liverpool and Valencia.

7 consecutive away defeats in the Eredivisie is the sequence Feyenoord ended on Sunday. The Rotterdam heavyweights avoided equalling a club-record eight straight losses on their travels - one suffered 30 years ago - in emphatic fashion, running out 4-0 winners at Roda JC for only their second victory in nine attempts this season. Georginio Wijnaldum headlined the success nine days before his 18th birthday, scoring the opener and setting up two more within a 15-minute spell during the second half. The result, Feyenoord's biggest success on the road since they beat Heracles Almelo by the same scoreline on 29 January 2006, was the joint-best away win in the 2008/09 Eredivisie.

3 own-goals against Tottenham Hotspur in the Premier League is the unwanted figure now haunting Liverpool's Jamie Carragher. The Reds defender's misguided header helped Spurs come from behind to win 2-1 on Saturday, which is the same scoreline his side lost by when he first netted at the wrong end at White Hart Lane in 1998. The former England international scored for Tottenham again later that same season, although Liverpool ran out 3-2 victors at Anfield on that occasion. Carragher has now scored a club-record six own-goals in all competitions, outranking another Liverpool legend, Ron Yeats.
