Mata maintains confidence in Chelsea strikers Ba, Torres
Both players are available for the FA Cup tie at Manchester United.
Mata said: "They are different players, Fernando is maybe a striker who likes to go deeper, Demba likes to play with his body and tries to be a nightmare for centre-backs. It's good for the squad to have different strikers like we have.
"We need to adapt ourselves to every game and every player, if we are playing with Demba or Fernando we have to play for them because they are our strikers."
