Chelsea manager Jose Mourinho insists "everything is open" for his side this season -- including winning a quartet of titles -- despite getting off to one of the worst league starts in club history.
Mourinho's men are 12th in the Premier League standings, 10 points behind leaders Manchester City, but are still alive in the Capital One Cup, FA Cup and Champions League tournaments. Despite their status in the Prem, the Portuguese coach believes anything could still happen this campaign for his club.
"We can win all four, we can lose all four. Everything is open. We are in October. Everything is open," Mourinho said on Monday.
"I think to win all four is something really amazingly difficult for everyone, even if you say Man City or Man United -- because they are at this moment top of the league -- even for them it would be very difficult to win all four.
"In England it's very difficult.
"Confidence is fundamental. We need to keep the tactical awareness, the tactical discipline. The spirit. The effort.
"The concentration, because concentration is fundamental. And step by step bring with good results the confidence levels up.
"And confidence levels are coming with results."
Chelsea bounced back from a disappointing 3-1 loss to Southampton with a belief-boosting 2-0 win over Aston Villa on Saturday at Stamford Bridge.
Mourinho sees the deficit his side currently face as not being insurmountable this early in the season.
"You know the difference between challenging for the title and for the top four is not so big," Mourinho said.
"It's not so big. It's not so big. I don't know if there is a margin for error.
"You have the top four of last season, you have Liverpool, you have Tottenham, you have a brilliant West Ham, you have sometimes a surprise like Swansea or Southampton.
"When you prioritise in this league you have a big risk, which is the risk of not winning the Champions League and [not] finishing top four and not playing Champions League the next season.
"So we cannot prioritise in this league. We have to go all the way and make sure we finish top four."
Chelsea will now shift their attention to the Champions League, where they sit third in Group G, a point behind Dynamo Kiev and Porto.
The Blues travel to Kiev on Tuesday to take on Dynamo, who, after last playing on Friday, will have a day's rest advantage over the defending Premier League champs.
"When you play Tuesday, the fact one team played Saturday and the other one played Friday, we're already losing 24 hours of an important recovery," Mourinho pointed out.
"We have to compensate that with tactical understanding of what we have to do, have a real tactical plan to compensate that.
"And the players to have, like they showed today, a fantastic spirit to try to get the result, because we are not on the limit situation in the Champions League, far from it.
"Even if we lose this match we still have nine points to play and to make a possible 12. In these two matches against Dynamo if we can have four points, the situation is much more comfortable."
