The Catalan giant is reported to have agreed a deal worth up to £142million with Liverpool to bring the Brazilian playmaker to Camp Nou, after a series of bids failed in August.

Coutinho will be formally unveiled on Tuesday (AEDT), with a photo shoot on the Camp Nou pitch to be followed by a press conference.

But Barca offered a glimpse of Coutinho in Barcelona colours in a video posted to the club's official Twitter account after the home win against Levante.

Coutinho is shown walking out on stage and posing for the cameras, waving to the photographers and offering a double thumbs-up for the flashbulbs.

The 25 year-old then sent a message to his new club's fans ahead of Monday's formalities.

"Hi Barcelona fans, I'm already here," Coutinho said. "It's a dream come true and I hope to see you tomorrow."

Without Coutinho, Barca beat Levante 3-0 to stretch their cushion at the top of the LaLiga table to nine points, with Lionel Messi, Luis Suarez and Paulinho on the scoresheet.
