Real Sociedad boss Philippe Montanier has criticised his side despite picking up seven points out of the last 10 available.
The Erreala are currently sixth in the table and could go into the Champions League places if they defeat Real Betis on Sunday.
But the French tactician has insisted that his team can still improve.
“I am picky and I think there is more to come from us,” he told a Press conference. “We have to give our maximum in every game – and only then can we continue this run.
“Real Betis are a team with great quality and will certainly be a danger for us. They have some brilliant players and we have to treat them with respect.”
