Robert Lewandowski feels like he has been at Barcelona "for months" after making his first appearance for the Blaugrana in Saturday's El Clasico win against Real Madrid.

The exhibition game at Allegiant Stadium in Las Vegas was decided by a wonderful goal from another new man, Raphinha, as Xavi's side ran out 1-0 winners.

Lewandowski could not find the net on debut but saw a fierce strike at goal pushed away by Madrid goalkeeper Thibaut Courtois in the first half.

The Polish striker only officially became a Barca player last week, but explained after the game to Barca TV and TV3 how settled he is already feeling.

"Although it was a friendly, the Clasico is the Clasico and it is always different and special, and we are very happy with the quality and intensity that we have shown," Lewandowski said.

"I'm very happy to be here and to be part of this team. I don't feel like I've been with the team for days, it feels like I've been with the team for months. I feel very supported by both my team-mates and the staff."

Despite their well-reported financial issues, Barca have been very active in the transfer window, bringing in Lewandowski, Raphinha, Franck Kessie and Andreas Christensen so far, while also being linked with a move for Jules Kounde from Sevilla.

The former Bayern Munich hotshot is anticipating a successful first campaign in Spain, and discussed the winning mentality at his new club.

"We always think about winning," he added. "We have a very winning mentality, not only in games but also in training.

"We have the opportunity to look forward and think that this can be a great season."

Barca begin their LaLiga campaign at home to Rayo Vallecano on August 13.
