Manchester City boss Pep Guardiola says Rodri will be key today against Arsenal.
City can go top of the table with victory.
Guardiola said: Rodri is so important.
In the big clubs, when you try and win big titles and have big targets, you need incredible players, characters and no injuries and then the situation is in your favour.
Since Rodri has arrived, he has shown how he has grown up - though in terms of mentality, he has always been so strong.
What can I say because I've said it so many times? He's a really important player."
