Sergi Roberto has returned to Barcelona training after a month out.

The defender took part in Thursday's session and could be in contention to face Celta Vigo on Saturday, Barcelona's last game before LaLiga's winter break.

Roberto's fellow right-back Nelson Semedo also trained, boosting Ernesto Valverde's defensive options heading into 2019.

However, centre-back Thomas Vermaelen has been ruled out for a month after the Belgium international sustained a torn calf.
