He’s back – Lionel Messi starts first game since injury and immediately bags two goals in Barca thrashing

The way Barcelona pressure the opposition as a team is the key to their success, coach Luis Enrique said after their 6-1 demolition of AS Roma in the Champions League.

Last season's treble winners were at their breathtaking best with the fit again Lionel Messi back in the starting lineup and helping them cut open Roma but Luis Enrique focused on their work rate.

“We go into each game with the knowledge that we need to pressure and the more that you do that then the better you get at it,” he said after his team secured top place in Group E with a match to spare.

“We found it easy to find space and we had a lot of possession. It is not easy to keep pressuring but this is what we are good at as a group and it is the key.

“Messi has fitted back into the side, I saw Suarez pressuring after 92 minutes, Neymar pressuring and it is the same as we have been playing before. All the team attacking and defending as a line.”

Suarez hit a brace and set up a further two for Messi who began his first game since picking up a knee ligament injury in September and looked hungry to get back among the goals.

There were also goals for Gerard Pique and Adriano while Roma's only reply was from Edin Dzeko in stoppage time.
