Ba's last treble came for Hoffen-heim against Stuttgart two years ago in the German league.
Demba Ba: “As a striker it is always important to score the first goal for your club, the sooner the better.
“It didn’t play on my mind though, I was more focused on getting my sharpness back in this game.
“Even if I had not scored a hat-trick I would still have been happy as I felt sharp.
"That was my goal. My team-mates were really happy for me and all signed the matchball.”
