Manchester City boss, Pep Guardiola has given reasons his side lost in the second leg of the Champions League round of 16 at home against FC Basel on Wednesday.
Manchester City still progressed despite the loss having won the first leg 4-0 in Switzerland.
They now join Juventus, Liverpool and Real Madrid in the draw for the next round.
Pep Guardiola’s City side, who are 16 points clear in the Premier League, suffered a shock defeat at the Etihad despite Gabriel Jesus’ early opener and the Spanish coach said his team forgot to attack in the second half.
Speaking after the match Guardiola said, “I’m so happy to be in the quarter-finals because it’s quite new for us.
“Tonight, we forgot to attack in the second half. We have to pass the ball to attack, not pass to pass.
“We forgot to try to go through and make a moment, runs in behind.
“Some players were tired. When you make changes, your level isn’t the same.
“Congratulations to Basel. It’s not a problem to concede those two goals.”
