Of course, Kasey is in a fairly good position to judge as he was a member of the then Leicester side, and knows that opposition teams are likely to have their work cut out at St Andrews - the venue we head for on Saturday.
"They are having a good little run," pondered Kasey. "A good hard working team - Steve Bruce has got them going. They remind me a lot of Leicester in my first season there. They seem very committed and work hard for each other.
"We have to go there and match their workrate if we want to get something out of the game."
Kasey's view on the Birmingham-Leicester likeness has also recently been mentioned by current Blues midfielder, and his former Foxes team-mate, Robbie Savage.
"I didn't hear that from Rob, but that's what I reckon from what I've seen. It does look that way, they are defending well with numbers and have the workrate to get into positions where they can get the odd goal.
"The game against Sunderland looked like a typical Leicester performance from five or six years ago."
On the subject of Savage, Kasey feels that he was the ideal player for Birmingham to recruit in order to make a positive impression on the Premiership.
"That's it," he added. "You know you are getting someone who is going to give you everything every time he is on the field.
"When somebody is running like that it is very hard for you not to join along with him.
"He is not the most popular man around, but he's always popular with the teams he plays for and that's the most important thing."
Kasey Keller can see a similarity between the current Birmingham side and Leicester when they were first promoted.
