"I think losing this LaLiga Santander would be very foolish with the points advantage we have," Alba told the 'Vamos' show on Movistar Plus.
"But there are still many points [available] and we have to continue."
On his new deal to 2024, Alba continued: "The club wanted me to stay and so did I.
"It is the club of my life and, although late, everything was done in the best possible way.
"We are all very happy."
