Chelsea boss Frank Lampard knows fans were frustrated during their 1-0 win over Newcastle United.
A Marcos Alonso goal overcame a difficult opposition side and made it five wins in a row for the Blues.
Lampard said: "The second half was the most pleasing thing. It was a good test for us today. We changed things a little in the second half and we showed a little more flexibility and creativity.
"We were upbeat, we had urgency, the tempo was good, and that got us the win.
"We want to score goals. You can see the fans - I think they're happy with what they're seeing at the moment. We want more.
"If we want to keep moving up, we can do better. So far this season, though, things are going well."
On Ross Barkley's injury, he added: "It's an ankle injury. We need to assess it and see how bad it is."
