In a career spanning over nine years, Mahmudullah has been well-known for his ability to bat at any position.
But he has yearned for a regular spot in all formats of the game.
"In which position I will play depends on what the team wants from me, but I am feeling comfortable batting at four right now," Mahmudullah said.
"I am always a team player. I will try to do well in whichever position the team wants me to. But at the moment I'm feeling good at number four."
But the 30-year-old batsman recent knocks suggest he is ready to settle down at four, because he has scored 593 runs in 12 innings - including two centuries and five half-centuries - at an average of 74.12 playing in that position.
No other Bangladeshi batsman has such good average at any one position.
He hit back-to-back centuries in the 2015 World Cup in Australia batting at the same spot.
