With only six games now remaining it would take a remarkable loss of form for Barca - who have won 27 of their 32 league games this season and lost just once - to be denied the title, but Ramos has pledged to continue pushing as long as they can.
"Whilst no team has been mathematically crowned champions we are obliged to carry on and put Barcelona under pressure," said the Spain international.
On Wednesday they play Barca again in the Copa del Rey final, while they also face the same opponents in the Champions League semi-finals.
"We have a large squad with quality players. Everyone on the team has responded whenever they've been given a chance to play," he added.
