Chelsea winger Pedro believes that his team's reaction to recent setbacks will determine how their season unfolds.
The Blues lost 6-0 to City in the Premier League, along with a 2-0 humbling at home against Manchester United in the FA Cup.
It has led too much disconcertion among Chelsea supporters, especially against boss Maurizio Sarri.
But Pedro believes the players have the quality to react.
"There is an important game in the Europa League for us, and after the final against City," Pedro told Chelsea's official website.
"The most important thing now is to stay calm, train really hard and recover our best football and our best feeling, because if not we are in trouble.
"It was a very bad day for us, for all the team (against United). It's a difficult situation. In the first half we played very well, we created chances to score one goal, but they had two situations and scored two goals.
"The most important thing was to do a good job creating chances with the ball in the second half, but we couldn't do it and for this reason it was so difficult for us to come back."
