Chelsea boss Jose Mourinho says the 4-1 win away at Walsall on Wednesday night was not as easy as the scoreline says.
The Blues produced a very good performance to move on to the next round of the League Cup.
But the Portuguese says his players had to be fully focused to take the win at the Bescot Stadium.
"It was not easy," Mourinho told reporters.
"We started very well. Immediately we had one or two chances, we scored the goal and we showed them that despite the fact they are a good side and they play good football we were not here to make mistakes and throw the competition away.
"When you start the season with bad results like we have, we could not lose against a League One team. You can do that when the season is fantastic and you are top of the league, but to lose a game against a League One team now wouldn't be good for us.
"We don't need that bad feeling, we need good feelings. The team was strong and played well. I'm happy with the result and individually it was good for the players too.
"John [Terry] was solid, normal, no problem. We brought a good solid defence. The midfield was really good. Mikel and Ramires played amazingly well.
"It was a good game for Falcao, a good 90 minutes- important for fitness. He worked a lot, ran a lot, moved a lot. He was in the game a lot. For the first time this season he was on the pitch for a long, long time so it was a good game for him.
"Kenedy played well. He was having pain in one calf, so I had to take him off, but a nice performance for him, good experience, more minutes on the pitch. It was good for all of them."
