UEFA suspension rules explained with Real Madrid and Man City stars at risk of Champions League ban

Taking a 3-2 lead back to the Santiago Bernabeu, Los Blancos will be slight favourites to reach the last-16 potentially setting up an all-Madrid tie against Atletico.

Though, disciplinary issues could prove problematic, with the Italian tactician having already had to deal with numerous suspensions this season and a number of players are facing a ban ahead of a last-16 clash.

In fact, Ancelotti will need to have a word with a few of his players, urging them to tread carefully in the second leg, whilst also staying calm himself as he is one yellow card away from a touchline ban.

In the Champions League, a player must receive three yellow cards, of which none result in a red card, to be suspended.

After receiving three yellow cards, “any subsequent odd-numbered caution” (fifth, seventh, ninth etc.) will result in another suspension.
