Leeds manager, Jesse Marsch, says he's excited for the "massive" challenge of trying to win the FA Cup. They take on Championship side, Cardiff City, in the third round in the Welsh capital this afternoon.
After seeing cup upsets already this weekend, Marsch doesn't want his team to fall to lower league opposition. Seven other FA Cup ties are taking place.
Bristol City are underway against Swansea with the Welsh side leading 1-0 and Derby County are hosting Barnsley. From 2pm, Hartlepool United go head-to-head with Stoke City, Norwich City host Blackburn Roves and Stockport County are at home to Walsall.
In the later games, it's Aston Villa at home to Stevenage and Manchester City take on Chelsea. There's a double header at Croke Park in the AIB All-Ireland Club Senior Football Championship.
