Arsenal midfielder Santi Cazorla has urged his teammates to cut out the mistakes, or risk seeing Chelsea romp to the Premier League title.
Arsenal let a lead slip for the second time in a week to lose 2-1 at Swansea City last Sunday, just four days after surrendering a three-goal advantage to draw at home to Anderlecht in the Champions League.
Arsene Wenger’s side have also dropped points from a winning position against both Leicester City and Manchester City in the league this season, while they needed a last-minute equaliser to claim a 2-2 draw against Hull City last month following another poor defensive showing.
"We are not in a good moment," Cazorla told Spanish news outlet El Confidencial. "These are mistakes we cannot commit if we want to fight for important things.
"It has happened to us several times already and we just can't keep doing that.
"In the league, Chelsea is now the most reliable, most consistent team. The strongest team. It is true that today they are the favourites to win the league."
Cazorla also stressed, though, that the Gunners’ squad has been hit hard with injuries, and remains at a loss to explain their bad fortune in the fitness department.
"It is something that surprises me,” he said. “There are always mishaps, like [Theo] Walcott, for example, or you twist an ankle. But the constancy of tears, to see people outside the team a long time, that makes us much weaker.
"We don't have all our players in the best possible condition and ultimately it makes the team more vulnerable. We hope that we can change this plague of injuries."
Things appear to be improving on the fitness front, however, with Walcott returning to action over the past week, and Olivier Giroud also resuming training from his broken ankle well ahead of schedule.
Nevertheless, key-men Mesut Ozil, Mathieu Debuchy and Laurent Koscielny are still sidelined, while there are fresh rumours that Abou Diaby has suffered a further setback in his bid to return from his hamstring injury.
