McLaren says Fernando Alonso will "maybe" be trackside at the Barcelona test next week.
Earlier, there was speculation the now retired-from-Formula 1 Spaniard could actually test for the Woking team this winter.
Spanish reports, however, said those claims were wide of the mark, even if Alonso will be in the city for the Mobile World Congress event next week.
"Fernando is part of the McLaren family. Maybe he'll come here next week," sporting director Gil de Ferran told El Mundo Deportivo newspaper.
