I am going to look through the game for spelling mistakes and text that is worded wrong.
I will post what i find here.
In Free Agents it says this

Should say
In the Free Agents Market you will find 3 new players every day and the old ones will disappear. You can increase the number of available players by building a Level 2 Club Base of higher. (New players appear after 02:00)
also i posted this topic before

--------------------------------------------------
When you go to Team Club Colors is spelt wrong that is the British American way the English way is Club Colours

here is the English description for the European Lv 3-5 cup
European Professional Cup for levels 3-5. All European regions of the game are involved.

I know its no biggie but NorthKorea in the profile is written without space lol.

http://11x11.com/xml/main/rules.php?id=3 there is a spelling mistake - "Generell" Terms, should be General

I think this is the place to add this.

In the statistic tab of the 2d view of a match the foul and yellow card are mixed up.
Also, there is a "YELLOW/Red card" section and a "Reds card" section. I think the first one should be Yellow card only.
