Loic Remy believes Chelsea are still well-placed in all competitions and can win the quadruple.
Speaking to the London Evening Standard, the French international said the Blues are focused on winning every competition they enter, with Chelsea going strong in the Premier League, FA Cup, Champions League and League Cup.
Jose Mourinho's team are currently top of the table, but level on points with Manchester City. In the Champions League they will face Paris Saint-Germain in the first knock-out round while a 3-0 win over Watford in the FA Cup secured their passage to the fourth round.
Defeat to Tottenham followed a draw against Southampton at St Mary's Stadium, which meant an eight-point Premier League lead at the summit was swiftly cut down over the festive period.
But Remy thinks Chelsea are over that brief run of bad form and are now back on track for a potential quadruple bid.
"It will be hard but we want to win every competition," Remy said. "That's where the mentality and quality of the squad can make the difference. Every player has to be ready.
We just try to be a strong squad because a lot of things can happen in the season. We are just focussed on winning games. - Loic Remy
"The mood is really positive. We are still focused on all the targets. Every team will be in trouble at some time and I hope our is behind us now with the last two games.
"There is no problem inside the camp, the players are still happy at training. We have shown everyone that we can react after two bad results.
"Was our confidence badly affected by what happened at Tottenham? No. We are still in first and top of the Premier League. We have qualified for the next round of the FA Cup, so there is no point to be negative or anything like that.
"We just try to be a strong squad because a lot of things can happen in the season. We are just focussed on winning games."
