The midfielder gave another accomplished performance against the German side, beginning on the right of midfield and looking impressive along side Gary Speed in the middle after Kieron Dyer had been replaced by Nobby Solano.
"It was good to get a game and a start obviously," Kerr told the Evening Chronicle.
"We got a 3-0 lead and then it came down to being professional and keeping the lead.
"The second half performance wasn't as good as the first half. We just kept it tight and got the victory we needed.
"It's four wins from four starts and long may it continue. It's great to begin games in the league and it's another step to get a start in the Champions League.
"As I've said, I just hope it continues and I keep improving.
"I would say it's probably my best performance. As each game goes by I've been getting that bit more confidence. Another three or four games I'll be at my very best."
The Scotland Under-21 international will certainly be awaiting Sir Bobby’s selection announcement for the Chelsea game on Saturday with some interest.
While Nobby is certainly first choice on the right of midfield Kerr can count himself unlucky if he finds himself back on the bench for the Premiership clash.
