Watch: Manchester City prepared for 'aggressive' FA Cup tie at Cardiff City - Guardiola
Premier League leaders travel to the Welsh club aiming to advance to the fifth round.
Manchester City manager Pep Guardiola has said his side face a "complicated" challenge when they travel to face Championship club Cardiff City in the FA Cup fourth round on Sunday.
City, with a 12 point lead at the top of the Premier League table, through to the League Cup final and into the knockout stages of the Uefa Champions League, remain in the hunt for all four tropies.
Next up for Guardiola's team is a trip to in-form Championship club Cardiff, and the Catalan is braced for a tough test at the Cardiff City stadium.
"They are I think second or third in the Championship. And playing away - so it will be tough," Guardiola said. "We know exactly. Today we started to speak about them and they (the players) know exactly how complicated will be the game.
"It will be so tough. We know that. So we play away a team that is in top form. Making good results. Playing the way they play so good. Second balls - tall team - set pieces - so aggressive in one-against-one. If you don't play quick with the ball, you will be in trouble.
"You have to avoid the contact as much as possible. Defend high because if you defend in the box, they are so strong. And use your quality to try to do our game."
