Carlo Ancelotti was more than satisfied with his side's clinical victory over Porto as the Blues ensured they will finish top of Group D.
Nicolas Anelka stooped low to head home a cross from Florent Malouda in the 69th minute to wrap up the win. It was the third time Chelsea have defeated European opposition by a solitary goal and on each occasion this season it was Anelka who provided the matchwinner.
"It was important because it was our objective to finish top of the group. We did very well because it is not easy to win here," said Ancelotti.
"The team played well. We took some risks in the first half but the second half was better and we deserved the victory. The team showed courage and personality, not all the time, but in spells.
"We are in a good moment and it is important to keep this high. The players are in a good condition mentally and we know we have a difficult game against Arsenal on Sunday but it is a good time to play against them."
More significant in terms of their clash with Arsenal was the news that injured midfielder Frank Lampard could be fit to face the Gunners. Lampard injured his thigh on England duty and has since undergone placenta treatment in Serbia.
Ancelotti revealed: "He has trained for the last two days and will train with the team on Thursday. We hope he will be fit."
Captain John Terry insisted Chelsea will be in confident mood going into Sunday's game after overcoming Porto.
"It's always going to be difficult coming here, they are a very good side with good players. I thought we dealt well with it and did what we had to do," said Terry.
"We looked confident, we're playing with confidence. We've got some tough games coming up, we need to regroup now and make sure we're sharp for Arsenal. It was a good performance."
