 If you liked
Whistle!

 ...then you might like
Haikyuu!!

Both are light-hearted sport manga where main character is little too short and considered to be not a worthy opponent. Yet they have something that a lot of other players do not have.
Both series have those ''wow'' effects where players do something cool and unexpected + teamplays and likeable characters :P
Haikyuu is volleyball and Whistle is football themed.
