Peterborough United’s midfield magician won’t be making the same mistake again ahead of the 2015-16 season.
The 23-year-old Turkish playmaker admits he approached his debut campaign at London Road with unrealistic expectations and his form and health suffered as a result.
But Oztumer is convinced he now knows what it will take to become a successful player at League One level with Posh.
Former Posh boss Darren Ferguson signed Oztumer from Ryman League club Dulwich Hamlet on a free transfer last summer.
“I went from training twice a week at Dulwich to twice a day at Peterborough,” Oztumer stated.
“And my body just couldn’t take it. It’s why I picked up an injury before the season started and why I couldn’t get into the starting line-up for a while.
“It was a very frustrating time as I had wanted to get into the team and blow everyone away with my performances.
“I know now that I was being unrealistic and I will learn from it.”
Oztumer scored 33 goals in 49 appearances in his final season for Dulwich.
He was a cult hero at a club that christened him ‘the Turkish Messi.’
Oztumer’s form had attracted the attentions of several Football League clubs with Luton Town going as far as giving the 5ft 3in star a full medical.
Oztumer started just 12 games in all competitions for Posh last season and scored just once, a sublime strike direct from a free-kick in the 2-1 League One win at Leyton Orient in December.
“That goal was the obvious highlight of my season,” Oztumer added.
“It was an up and down season for me. I had some good moments and some not so good moments.
“It took me a while to break into the side and then when Dave Robertson became manager I was left out for about 10 matches before playing again towards the end of the season.
“People talk about formations a lot and the fact that I am apparently better suited to one way of playing than another.
“But formations don’t really bother me. I played on the left of midfield, the right of midfield and in the centre last season, and I played up front.
“I don’t care where I play because when I get on the ball I just want to create chances, score goals and generally play in an entertaining way.
“I want to make things happen and I think that’s what the Peterborough fans like to see.”
Oztumer certainly has a large fanbase for someone with so few appearances to his name.
He was a regular winner of the sponsors’ man-of-the-match award at home matches last season.
Oztumer is also supported en masse by his family and friends at every match.
“I enjoy wonderful support from my family,” Oztumer said.
“It’s been that way throughout my career. I’m very grateful to them.
“The Peterborough fans have also been very good to me and I hope to repay them by playing better next season and by helping the team get to the play-offs or even promotion.”
