Rodri said: "I think it is going to be a tough game.
“They are so strong; they are one of those very English teams, so we are going to do our best.
“We obviously need three points to stay in touch with the leaders and we don't need to see that they beat United to know that they are a good team.
“One thing I have quickly learned is that all the teams in the Premier League can beat you.
“We lost against Norwich who are at the bottom of the table and we lost against the leaders, so everyone can beat you and that is the good thing about this league."
