Demba Ba knows his career at Chelsea will be judged on goals.

The former Newcastle United striker acknowledges that inside the box is where he will ultimately be judged.

"You know, I just do my job and, for a striker, the job is to help the team to win games by scoring goals first of all," he told Chelsea Magazine.

"It's not only about scoring goals, but it helps you a lot and it helps the team when you do so.

"Everywhere I went, that's what I tried to do, without being selfish in front of goal, but always for the team."
