This week's Anglo-centric collection of blunders starts with Artur Boruc, the zany Southampton goalkeeper whose moment of madness led to his most embarrassing incident of the season. Well, maybe his second-most embarrassing.
Elsewhere, we look at Merseyside misery for Joe Allen, bad behaviour in Cardiff and Nice, and the game where Tottenham Hotspur lay down on the field and let Manchester City walk all over them for 90 minutes.
Take a look at our selection the leave your comments below.
Before Saturday, high-flying Southampton had only conceded five league goals, the fewest in the Premier League.
Goalkeeper Artur Boruc, however, added to his lowlight reel for the second time this season during the Saints' 2-0 defeat at the Emirates.
In the 22nd minute, the Pole showed us exactly why he isn't an outfield player when he tried to deal with a backpass by beating Olivier Giroud on the ground. He confused himself and gifted the Frenchman the opener that helped the Gunners open up a four-point lead at the top of the table.
To his credit, Boruc was able to laugh about it later on, comparing himself to Johan Cruyff on Instagram.
Liverpool's visit to Goodison Park was pretty entertaining. It was so good, in fact, that we should probably just stop football entirely and declare this Merseyside derby the winner of sports.
Someone who didn't emerge as a winner, however, was Joe Allen. Before Saturday lunchtime the Welshman had played only 34 minutes of Premiership football, and Liverpool fans were highly skeptical of his inclusion in the starting line-up.
The skepticism was proven to be valid when the 23-year-old was put through on goal in the 60th minute with the chance of making the score 3-1. Luis Suarez, who set him up, was completely free and Tim Howard dove the wrong way, but Allen still managed to shoot wide.
He probably won't want to watch the clip above again.
Celtic have a five-point lead in the Scottish Premiership following a 3-1 home victory over Aberdeen.
In the midst of the action, Efe Ambrose almost scored one of the goals of the season. Picking the ball up on the halfway line, the Nigerian defender decided to charge forward and go for glory. He beat five defenders before reaching the edge of the box, where he unleashed a very powerful shot...which landed somewhere near Row Z.
What a way to finish such a fantastic move. See a gif of the action here.
Before Sunday's match, Manchester City had scored 19 more Premier League goals than Tottenham (28 compared to 19), but they were below them in the Premier League standings.
On Sunday evening, City had scored 34 and leapfrogged over the Lilywhites thanks to their 6-0 annihilation at Eastlands.
Jesus Navas only needed 13 seconds to capitalise on a poor Hugo Lloris clearance, and a ramshackle Spurs side went on to concede a total of six goals—the same amount they had conceded all season up until this game.
Speaking to the BBC, Andre Villas-Boas said the Tottenham staff were "ashamed" of their heaviest defeat since losing 7-1 to Newcastle in December 1996, but according to the Guardian's tactics expert Michael Cox, it was AVB who should be facing the brunt of criticism for such a blunder-filled performance.
Nice were handed their fourth consecutive Ligue 1 defeat thanks to a 1-0 home defeat by St. Etienne, but the game was marred by crowd trouble from the outset.
According to the Guardian, travelling fans dismantled seats at the Allianz Riviera stadium and threw them at opposition fans an hour before the game, with the hooliganism resulting in nine injuries. The away fans were evacuated from the stadium before the match kicked off.
LFP president Frédéric Thiriez subsequently threatened a ban on away fans due to the incidents. Way to ruin the fun for everyone else, St. Etienne fans.
Manchester Utd were held at Cardiff City Stadium on Sunday thanks to a last-gasp equaliser from Bo-Kyung Kim.
Much has been made of the fact that Wayne Rooney was lucky to stay on the field after he clearly kicked out in anger at Jordon Mutch and received just a yellow card, but the men most worthy of seeing red might have been Gary Medel and Marouane Fellaini.
As Cardiff were preparing to take the set piece that resulted in their injury-time equaliser, the man nicknamed "The Pitbull" appeared to take at least two swings at Marouane Fellaini, justifying his terrifying reputation. Medel, however, appeared to be reacting to the fact that the Belgian had elbowed him in the head.
Lots of violence, lots of goals and lots of inaction from the officials in this match.
Crystal Palace managed a rare win at Hull thanks to an 81st-minute strike from Barry Bannan. Earlier in the game, a Hull attack was halted when Paul McShane clashed heads with Marouane Chamakh. The Moroccan international didn't really recover from the incident, and was seen bursting into tears shortly before he was substituted.
It's hard not to feel sorry for the poor chap—for this incident and his season so far.
