West Ham TV brings you another new feature this week as Mauro Zarate has set himself a big challenge.
The Argentine star reckons he is the king when it comes to naming which clubs south American players have played for.
We asked supporters on Twitter to submit their questions and try to catch the No10 out.
In the first edition of our exciting new feature, see how many the talented forward gets right and if you manage to beat him.
If Zarate fails to name all the clubs correctly, he has agreed to give away a prize.
So if you want to submit your questions, all you need to do is use the hashtag #CHALLENGEMAURO
