In away game against Schalke Guardiola because of Stones injury deployed tactics similar to game against Arsenal and played only three nominal defenders with Fernandinho playing as center back without ball and in more advance position in possession. Gundogan played as number six and David Silva and De Bruyne as number eight, In attack played Bernardo, Aguero and Sterling. City started to control ball from the start and in first minutes De Bruyne long pass to free Aguero resulted in shot that was blocked. City tried to attack from wide positions couple Sterling dribbles ended in dangerous low crosses that didn’t find City player. There were often miscommunication between City players and bad passes that ended good attacks. Schalke opened a lot of spaces for visiting team but last ball was lacking. Sergio Aguero struggled to link up with teammates and hold ball too much. City scored after Schalke lost ball near their box after trying to play from back and David Silva passed to Aguero who scored in empty net. City continued to enjoy most of possession but struggled to create great chance, golden opportunity arrived after Schalke lost ball again but City failed to materialize 3 vs 1 opportunity after Sterling bad pass to David Silva. Schalke attack were predictable and didn’t create any problems. Problems arrived when De Bruyne lost ball in middle of pitch and Schalke made quick attack which ended in shot that hit Otamendi hand. After consultation penalty was appointed, Otamendi received yellow card and Bentaleb scored it. Couple minutes later after Otamendi bad clearance David Silva fouled German player and when free-kick was played Fernandinho hold Schalke player and home team earned second penalty. Fernandinho received yellow card which will see him missing next CL game. Bentaleb again scored penalty. After half-time City played more aggressively and created immediately couple good opportunities but shots were little bit wide. Because of Aguero bad link up play away team didn’t create couple great opportunities. De Bruyne, David Silva struggled to create and Bernardo Silva on wing lack of speed made City predictable. Guardiola lack of changes given struggles was baffling, until Otamendi got second yellow card and was send off around 70 minutes Guardiola didn’t made changes. After that David Silva was substituted for Kompany and couple minutes later Aguero for Sane. Sane started to play on left wing and Sterling as center forward. After sending off City continued to have more possession and attack but struggled to create. Equaliser came after Sane amazing free kick from around 30 meters on 85 minute. Schalke after that started to play aggressively and City used that with Ederson long ball ended Sterling running behind Schalke defense and getting 1 vs 1 opportunity against keeper on 90 minute which he used. Last couple minutes City see off game and now are in great position to advance in quarter final but level of performance was low and Guardiola tactics left many questions.
