Chelsea's Andre Villas-Boas frustrated after Wigan setback
Andre Villas-Boas insisted Chelsea will "continue to fight" after they dropped two crucial points against Wigan in the race for the Premier League title.
Jordi Gomez's late equaliser cancelled out Daniel Sturridge's goal to leave Chelsea third place in the table.
"In the end we let it slip," said Villas-Boas after the 1-1 draw.
"We have a massive game against Tottenham on Thursday. We are in the right spirit and hope to go back to the good results."
Chelsea are six points behind leaders Manchester City but have played a game more.
Wigan had lost nine of their previous 12 league games going into the match and Villas-Boas felt his side should have held on to their lead at the DW Stadium.
"We're not satisfied but we'll continue to keep pushing, our confidence will not be affected," he said.
"It was a hard-fought game with many chances on both sides, maybe more from Wigan. Wigan at that time [when they scored] had momentum and the crowd behind them and got the goal that they deserved.
"It is always difficult to play away in the Christmas period away from home."
Wigan manager Roberto Martinez labelled his struggling team's battling performance "perfect" and insisted his side deserved a share of the spoils.
"We had more corners, better possession and more chances than Chelsea," said Martinez, whose side entertain Liverpool on Wednesday before facing Manchester United on 26 December.
"The performance was perfect from our point of view, the players were magnificent.
"Losing eight games on the trot was a real test, but the players overcame that."
