Barcelona coach Pep Guardiola reckons that his side must provide a professional performance if they are to ensure qualification for the semi-finals of the Champions League this week at the expense of Bayern Munich.
Guardiola's side destroyed Bayern 4-0 at the Camp Nou last Wednesday with a glittering display of attacking football, but despite the considerable advantage Barcelona possess, the coach is not taking anything for granted.
He told journalists at today's press conference, "We have a lead of four goals but we know that we need to do well. They will have a very strong opening few minutes and will play with great intensity.
"Our objective is to get a goal. If we manage to score we will bring the semi-finals even closer."
Guardiola is also of the opinion that although his side must be wary of conceding he will ask his players to continue to employ his offensive philosophy, and believes in this case attack is the best form of defence.
He added, "We are strongest when we go for the match, when we play in this manner.
"My players know there is still work to do. We come into the game with a good lead but this is another game. There are many different factors. This is not done."
