Allen revealed that he is very happy at his new club. The 26-year-old joined Stoke this summer from Liverpool for £13m. He's been playing since 2012 for Liverpool after joining the club from Swansea City.
The Welshman said in an interview that he felt he needed to move clubs for personal reasons.
He hopes to advance in the team and get more game time. Furthermore he said:
"Any player will tell you regular football makes tonnes of difference to the way you perform and the way you feel out on the football pitch. It comes to a certain stage in your career where, if it's not happening, then you have to go and seek it out.
He added that his former playing style didn't fit to Stoke, but now he changed.
"But the likes of Shaqiri, Arnautovic, Bojan, (Ibrahim) Afellay and (Giannelli) Imbula - players they have brought in - as well as others that were already there, (Glenn) Whelan, Jonathan (Walters) and (Peter) Crouch. The list goes on.
"It made it really appealing to me, and was one of the big reasons why I signed there. You have seen they have finished ninth three years running and they are not happy to settle for that".
