Pep Guardiola was “very, very happy” with Bayern Munich’s 6-1 win against FC Porto in Munich on Tuesday, “especially after recent weeks when we had our problemsscoring goals,” the Spaniard said. Bayern won the two-game series by an aggregate score of 7-4 after Porto won the first game, 3-1, in Portugal last week. Julen Lopetegui,Guardiola’s opposite number, bemoaned his team’s poor first half, in which the host jumped out to a 5-0 lead. He added: “We have to remember that in terms of experience, there arethree or four hundred matches’ difference between the two sides.”
