I have a page where I show the teams of a football club. I order these with 'order' => 'ASC'. But the problem is that the teams order like I want it to.

It orders like this: 
Team E1, Team E10, Team E11, Team E2

It must be like this: 
Team E1, Team E2 ..... Team E10, Team E11

What is the best solution to order this the right way?
