If the task didn't already seem daunting enough for the Manchester City squad, the warning words of Barcelona skipper Andres Iniesta will not have done anything to re-assure the Citizens that they can overturn a 2-1 first-leg defeat at the Etihad Stadium.
The midfielder says that his teammates plan to "make Manchester City suffer" through monopolising possession and "controlling what goes on at every moment." Vincent Kompany and co have duly been warned. However, Iniesta has also warned his teammates about complacency in the wake of their first-leg advantage, telling the press today that "it is a difficult opposition".
Following the return of Yaya Toure to the Manchester City squad following his suspension in the first leg, the Barca man also highlighted the importance of "minimising the potential" of his former teammate during the return leg at the Camp Nou.
Iniesta focused on Man City
With Real Madrid still on Barca's tail despite suffering recent setbacks against Athletic Bilbao, Iniesta refused to be drawn into talk of prioritising El Clasico this weekend over the Champions League return at the Camp Nou.
He told reporters: "It is true that after tomorrow we have a very important match on Sunday against our main opponents in La Liga in Real Madrid, but we don't think beyond tomorrow."
Man City facing massive task
This having been said, it seems that Manchester City will have to defeat a full-strength, motivated, concentrated and in-form Catalan outfit if they are to progress to the Champions League quarter-finals for the first time.
Barcelona manager Luis Enrique was quick to echo his skipper's words of caution ahead of the tie by saying that "it would be dangerous to take anything for granted from the result in the first-leg." Their opponents have been warned; they will not face a complacent Barcelona side keen to rest on their laurels.
For this reason, it will take something truly special for the Premier League champions to knock the Catalans off their perch on Wednesday evening.
