My Diary - a week after

 I haven't written in my diary for a few days. This week I was very busy with my job.
Today is Saturday and I am more freer. I have just done the  made lunch for my daughter, she will be back home soon from school soon.

After lunch I'll go to the stadium to watch the match of my favourite football's team.
I hope that today they win!
Then, in the afternoon, I'll go to  the cinema with my family to watch "The Brave", a new Walt Disney production.
Yes, probabily it will probably be a good day!

Note: I have rearranged the location of some of your words to reflect the usual structure of an English sentence. I have crossed out some words and changed them for words that are more common. Football teams are usually referred to as they.

With this sentence "Today is Saturday and I am more free", I did a minimal change. Freer is a word but you would usually see a  sentence  like "Today is Saturday and I have more free time". This is using words close to yours.
