Not only did Ajax outplay Manchester City on the pitch in their last meeting but Frank de Boer out-managed Roberto Mancini as well.
De Boer's 4-1-4-1 formation caused trouble for the 4-2-3-1 that Mancini sent out at the Amsterdam Arena two weeks ago.
Mancini was aggressive with his starting lineup by starting Yaya Toure in the central attacking role in midfield instead of being one of the two defensive midfielders.
Along with starting Toure back in his regular position, Mancini must avoid going for three defenders in front of keeper Joe Hart for the whole match.
Mancini has had a tendency during the season to switch to three defenders and send a substitute on, like Aleksandar Kolarov, to go forward in attack when City are looking to win matches.
De Boer's strategy is quite simple on Tuesday, keep using the formation that works best for the club, which is the 4-1-4-1.
The center of midfield that includes Lasse Schone, Siem de Jong and Christian Poulsen is one of the strongest parts of De Boer's lineup.
Poulsen usually sets up as the player in front of the back four while Schone and De Jong play in the center of midfield.
Sticking with just one formation during a match is something De Boer will not be concerned with; for Mancini it could be the one decision that either wins the match for City or eliminates them from the Champions League.
