Jose Mourinho warns Chelsea that they must focus on Saturday's game against Bradford to avoid a replay at Valley Parade.
The Blues are still involved in all four competitions this season and the Portuguese says the objective is to progress into the next round of the FA Cup.
"At this moment we have all the reasons to be smiling because we don't have injuries," Mourinho said.
"My team tomorrow will reflect the fact that if we lose the game, we are out [of the FA Cup] and if we draw we have to go to Bradford.
"We don't want to be out and if possible, we don't want a second match. My team will reflect our desire to go to the next round and the respect Bradford deserve from us.
"This season we have already played Championship and League One teams and I don't remember an easy game."
With a number of Chelsea players linked with a move away from the club, the Portuguese wanted to make it clear that his desire is not to sell any players this month.
"Our desire is to keep the same squad," Mourinho explained.
"[This] reflects we are happy with the players and the work we did in the summer to prepare for the season, and the trust we have in the group,' Mourinho clarified.
"I like [Andre] Schurrle and [Mohamed] Salah and I need and I trust them. I can't select the same 18 players every game and I can only start 11.
"Salah is not playing a lot, Schurrle is more than him, but they been involved in every competition including the Champions League. I count on them and tomorrow both are selected to play.
"The way Hazard and Willian are performing, with the stability of their performances in attack and defence and transition, unless I find a tactical system with three wingers it is difficult to be in front of them [for selection] because they are playing so well."
Meanwhile, the 51-year-old again insisted that he took the right decision in keeping 20-year-old Kurt Zouma at Chelsea instead of loaning him out last summer.
"We are impressed [with Zouma]," he said.
"We bought a talent but that talent was far from ready and at the beginning of the season people were thinking it would be better for him to go somewhere [on loan] and play.
"But we thought It was better for him to stay and learn here in this habitat where for sure he will be a player for many years. We are very happy with him."
