Newcastle striker Ba: Don't compare me with Man Utd's Van Persie

Newcastle United striker Demba Ba doesn't want to discuss comparisons with Manchester United ace Robin van Persie.

The two attackers face a shootout tonight.

But Ba insists: "I do not compare myself to others, I'm just trying to give everything when I'm on the ground. I'm attacking, I was asked to score, so whenever I'm on the field I try to do my job the best way possible."
