You don't need Comma(,) before 'because'

I enjoy playing (play the second verb should be in the 'ing form'= playing) football

I think 'I enjoy playing at football' is also correct.

Notes:

Hi Albert! Nice introduction! :)

Some comments about my corrections:

1) In written English, ALWAYS add a space after the comma ( , )

2) In the format "I enjoy ____", the second verb will always have an "ing" ending. For example, "I enjoy reading", "I enjoy cooking", or "I enjoy playing football". 

I hope this helps, and if you have any other questions you can send me a message and I will be glad to help you.
