The fatigue is beginning to show as the physical toll of playing so often in December intensifies. Especially for teams that are also competing in Europe. Of all the Premier League teams in European competition this season, Only Manchester City, Crystal Palace, and Aston Villa managed to win this gameweek. And two of those victories (Palace and Villa) required last-minute goals after an evenly matched contest. As the fatigue continues to set in and managers try to figure out better ways to navigate the season, here are the winners and losers from all the action this gameweek.

Fulham and Crystal Palace were evenly matched for all of ninety minutes on Sunday. However, Marc Guehi's header with three minutes to go stole all three points for the Eagles and moved them up to 4th place on the table after fifteen games. That feat in itself is quite remarkable for a club of Palace's stature, but even more so on account of the size of Oliver Glasner's squad. Typically, when midtable teams get into Europe, they struggle to balance the requirements of playing twice a week regularly, and the struggles are usually on account of not having the squad depth necessary to compete effectively on multiple fronts. Crystal Palace quite simply do not have the required squad depth. On Sunday, they played midfielder Christantus Uche as a striker for a few minutes because Mateta needed the rest, and they had no replacements on the bench. Depth issues notwithstanding, this team continues to punch above its weight, very remarkable indeed.

Arsenal have lost twice in the league this season, and on both occasions they were unfortunate not to come away with at least a point. A wonder goal by Szoboszlai downed them at Liverpool, and on Saturday, Emi Buendia scored with the last kick of the game to condemn the Gunners to defeat. The defeat itself is not the biggest problem; Arsenal are still on top and favourites to win the title. The problem is the potential psychological impact of defeat to Aston Villa at this point in the season. Aston Villa have posed a challenge to Arsenal in each of the last two seasons, and Arsenal need to beat them as much for the three points as to exorcise the psychological effects of always losing to this one team. This defeat will not only reinforce the psychological problems, but it also comes at a time when Arsenal are facing an injury crisis once again. Three senior centre-backs are currently out injured, and Trossard had to come off against Villa, having only come on at halftime. Arteta has it all to do if he is to keep his team motivated and navigate this period well.

That's four wins in the last five games for David Moyes's team now, a remarkable feat by Everton's standards. What's more remarkable about it is that they've kept clean sheets in every one of those four wins. This is a Moyes team at its finest, defensively resolute and able to get the goals needed to win games. The run of form has seen them climb up to 7th on the table, and the Toffees will be brimming with confidence as they face Chelsea and Arsenal in the coming weeks. Considering that Moyes was rumoured to have been brought in just to steady the ship before handing over the reins to another manager, he's doing remarkably well. He's moved the ship from relegation concerns to European spot conversations and, most importantly, to just about any Everton fan, above Liverpool on the table.

All the momentum from their hard-fought 1-1 draw against Arsenal seems to be dissipating. A dismal 3-1 defeat to Leeds was followed up this weekend by a dismal 0-0 draw with Bournemouth. Bournemouth have been very poor of late and have just one draw in their last five games, having lost the other four. These are the kinds of games Chelsea should be winning if they want to maintain their title charge momentum and capitalise on Arsenal's stumble against Aston Villa. That draw sees Chelsea slip to 5th and leaves them six points behind Arsenal, closer to Tottenham in 11th than Arsenal in 1st. Indeed, given that they play a very in-form Everton side next weekend, Tottenham could very well be above them on the table by the time gameweek 16 is over. Chelsea's title charge narrative is slipping away rapidly.

Arsenal have conquered the stumbling blocks of seasons past this season, beating teams like Fulham, West Ham, and Newcastle that have caused them problems in the past. However, they don't have an answer for Unai Emery's voodoo yet. Since leaving Arsenal, the Spaniard has haunted his former club nonstop, literally standing between them and the Premier League title more than once. This time around it was close, it took Emi Buendia with the very last kick of the game to condemn Arsenal to defeat at Unai Emery's hands yet again. And just to highlight the great work Emery has been doing, Aston Villa are now 3rd on the table, only three points behind Arsenal themselves. It's a pretty astonishing achievement given how badly they started the season with no goals and just one point after four games. However, Unai Emery has steadied the ship and turned things around. At Villa, he has become famous for derailing Arsenal's title charges, but he might be in a title charge of his own at the moment if his team can maintain this momentum.

Sunderland's loss against Manchester City means they are on a run of only one win in their last five games. That run has seen them slip all the way to 9th on the table after a start to the season that saw them go as high as 2nd at some point. A dip in form was always on the cards for the newly promoted club at some point, no one expected them to keep pace with the title contenders throughout the season. However, this dip has come at a horrible time for the club, given the congested December schedule and the fact that they are set to lose several key players to AFCON after next week. They're already beginning to falter, and they might have to navigate the toughest part of December's fixtures with a severely depleted squad. Pray for Regis Le Bris and his boys, things can get really ugly, really fast in the Premier League.
