The 26-year-old played 80 minutes for the Newcastle reserves in their 4-1 win over Middlesbrough last night.
Barton said: “Because of my past misdemeanours, it has been tough for me.
“The season starts here for me and hopefully it is a case of onwards and upwards.
“It’s the first game I have played, really. It is a starting point but I have trained hard.
“The aim is to turn in performances for the fans.
“I want to do it for everybody connected with the club — players, fans and staff, everybody I have let down in the past.
“I want to go on to start paying back my transfer fee, which I don’t think I did at any stage last year.”
