Another weekend in the books from the Barclays Premier League means another roundup of trivial facts and stats to garner. Here are five interesting facts from Matchday 4.

Swansea City, Manchester United and the Rule of Three

Swansea City, Wales’ lone team in England’s top flight, topped the Premier League’s most successful club over the weekend. Manchester United came to the Liberty Stadium with three successive clean sheets on record to begin the year, but fell to the Swans 2-1 after goals from André Ayew and Bafétimbi Gomis cancelled out a Juan Mata strike for the visitors. This is the third consecutive time Swansea defeated Manchester United in the Premier League, as each game resulted in a 2-1 scoreline to the Swans.

Jose Mourinho’s Recurring P Problem

Chelsea were defeated in a double milestone for manager José Mourinho against Crystal Palace. Saturday’s shock 2-1 defeat in Stamford Bridge was the prolific Portuguese manager’s 100th Premier League match at Stamford Bridge and 200th overall in the league. The interesting fact here is that Mourinho’s last seven defeats in the Premier League are from opposing managers whose surnames begin with P.

Stoke’s Rapid Reds

A nine-man Stoke City were downed by West Bromwich Albion 1-0 in Stoke. The double send-off for the Potters after 31 minutes was the the third-fastest in league history. This is also the tenth time a team had to play with nine men before half-time.

Arsenal Tightens Grip On Toon; An Unlikely Leading Scorer

Arsenal extended their winning streak over Newcastle United to eight over the Magpies in Premier League with a 1-0 victory over the 10-man hosts at St. James’ Park. Newcastle have failed to defeat Arsenal in their last ten Premier League matches, dating back to the 2010/11 season. The current leading goalscorer for the Gunners doesn’t even play for Arsenal; it’s Own Goal with two, one more than the only actual scorer on the team, Olivier Giroud.

West Ham’s Opening Aggression

West Ham United ended a 52-year drought over the weekend with a resounding 3-0 victory at Anfield over Liverpool FC. Another interesting mark was also set during the win. The Irons in 2014/15 were among the least carded teams in the Premier League, with 64 yellows and 2 red cards. A red card to Mark Noble at 78 minutes had already eclipsed this stat this season for the vistors, as they suffered their third red card of the young season.
