The Greek keeper is on loan from Coventry City to Cardiff City for the rest of the season and Dim told Sky Sports: "At the moment I have been very impressed with the whole set-up here and the squad as well, which has a lot of quality.
"The club matches my ambitions to play at the highest level, so things are looking good for me at the moment here, but things can change very quickly in football. We will see how things go in the next couple of months and take it from there.
"I wouldn't reject any offers from Cardiff because from what I have seen so far everything is in place here to go up this season, but we will see how things go from now until the end of the season. We will take it one game at a time and hopefully it will have a happy ending."
