Slovakian prospect Miroslav Stoch struck four goals in Chelsea's 6-4 victory over Ipswich.
"Attacking is what this team is like," Blues coach Paul Clement told the club's website after the game. "We have scored five at Port Vale, four against Shrewsbury, three away at Villa and six today. It is a very talented attacking team, just a bit too open defensively.
"We have got to learn to defend better because otherwise we are going to get found out in the big games, the important games. Obviously we will reflect on that and see how we need to defend better.
"But it is not just the back players, it is a collective thing, it is the forwards as well. We attack as a team so we need to learn to defend as a team.
"But it was a good game to watch," he added.
