The Blaugrana signed off from their famous stadium in style, with Gavi also netting in a comfortable win over their 10-men visitors on Monday (AEST).

In what was its final home game at their iconic ground before a temporary move to facilitate a lengthy renovation, Xavi's side ensured it bade it a fitting goodbye.

After losses against Real Sociedad and Real Valladolid, it also marked an impressive return to form.

Barca needed less than a minute to carve open their visitors, with Fati tucking away a Gavi cutback following a neat Robert Lewandowski ball into the box.

Matters soon worsened for Mallorca, when Amath Ndiaye saw his yellow card upgraded to a red by VAR for a shocking foul on Alejandro Balde.

Fati doubled his tally after that with a close-range rocket off Lewandowski's deft one-touch set-up, and Barca never looked like losing control from there on out.

Mallorca dug its heels in, but even then remained under siege, with Jules Kounde hitting the bar with a header shortly after the restart.

Lewandowski crashed a free-kick against the woodwork too, but Barca finally found their third when Gavi lashed a low finish beyond Dominik Greif.

There were standing ovations for Jordi Alba and Sergio Busquets on their final home appearances, with the Camp Nou crowd rising to salute the club legends.
