Sean Dyche’s men were well and truly ripped to shreds by a blistering Chelsea display.
Hakim Ziyech put the visitors in front with his second goal for Chelsea inside 26 minutes before Kurt Zouma met a Mason Mount corner to double the Blues’ advantage midway through the game.
Timo Werner wrapped up the points with a sumptuous finish on the 70th minute mark to send Burnley bottom of the league.
In an interview with the media after the game, Lampard labeled his side’s victory as a complete performance and insists Chelsea are doing something positive.
"It was a very complete performance from us. It’s a difficult place to come. They make it very difficult for teams and they’ve been unlucky in games. We controlled massive parts of the game, so I’m very happy,” the English coach said.
"I was always aware at the start of the season that it wasn’t going to be easy. It was asking a lot for us to fly out of the blocks, but performances like this show that we’re doing something positive. We need to get our heads down and keep working hard.
"It’s tight everywhere. There are games where we’ve been frustrated and dropped points. It’s happening everywhere in the Premier League."
Pulisic was named in the starting lineup but picked up an injury during the warmup.
Lampard added: “He felt something on his hamstring. We tried to manage him in midweek, but we’ll see what happens in the next 24 hours. We’re talking minor, nothing serious.”
