Barcelona manager Luis Enrique has said that there is still room for improvement in his team, despite their 6-1 win over Roma this evening.

The European champions ensured their progress to the last 16 of the Champions League by easing past their Italian guests, just days after cruising to a 4-0 win over fierce rivals Real Madrid.

"Perhaps Roma arrived in our best period of form this season and it's always difficult for everyone to play here against us," Enrique told Mediaset Premium.

"Are we the best Barcelona in history? Many journalists ask us that, but we are not interested. We are focused only on doing the best we possibly can and win as many trophies as possible.

"It's still the start of the season and we can improve in certain areas."

Barcelona are back in action on Saturday afternoon with a league meeting against Real Sociedad.
