Meaning of 小せェサル in the following sentence


A Japanese boxer that has never been beaten in Japan is fighting against a
Cuban boxer in his first match against a foreigner. After easily taking the
lead of the match, the Cuban boxer says:

> この **小せェサル** の島国にはいなかっただろう テメェを支配出来るボクサーは

I know that サル is used as an offensive word meaning "idiot, hick", but used
together with 小せェ could it be an offensive way to say "puny"? Please consider
that previously in the manga (see [here](https://i.stack.imgur.com/NBWV6.jpg)
and [here](https://i.imgur.com/RZtDUw7.jpg)) he made a derogatory comment
about Japanese physical features.

you for your help!




I think it's not 小せェサル but [小]{ちい}せェ(サルの)島国.

ちい **せぇ** is a rough, slangy pronunciation of ちい **さい**.  
(See: [What does こまけー mean?](https://japanese.stackexchange.com/q/3746/9831) /
[What is じゃねぇか? What is its original
form?](https://japanese.stackexchange.com/a/18458/9831))

> この + 小さい + サルの島国  
>  this little island of monkeys

小さい describes （サルの）島国. It's probably referring to Japan.

I think サル here is used as an offensive/derogatory word for Japanese people.
