Poyet has joined the Championship outfit on a season-long loan over the summer, as he looks to get regular competitive minutes under his belt.
And the Uruguayan believes that the opportunity to play first-team football is a good one for him, as it is aiding his development.
"The Championship is a great league to learn in, with so many games and a high quality," he said. "I want to feel the pressure and get minutes. There's a good feeling at the club and I've clicked with the gaffer. So I'm pleased to get the chance to play here. It's the best way for me to develop."
Poyet actually played five games for West Ham prior to his loan move to MK Dons, as he was a key part of their Europa League squad.
There are high hopes about the central midfielder's future at Upton Park, but his chances of breaking through this season appeared slim and Bilic clearly decided that he would be better off moving elsewhere on a temporary basis.
West Ham are stacked with options in midfield, and Poyet was unlikely to dislodge some of his more experienced Hammers teammates in the starting line-up.
While on loan with MK Dons, Poyet has gone straight into Karl Robinson's startin XI and has made nine appearances already this term.
