Spain international Iago Aspas showed his concern over Celta's negative mindset after their sixth gameweek without a win.
"We have to have to try and work harder, starting on Monday, but Real Sociedad were far better. There is nothing left but to knuckle down and keep working. As I said to Denis, we lack spirit and experience, above everything else though we can't concede goals like the second and the third one tonight, and we have to create more chances", he said.
The Celta captain admitted that they are in a "difficult" position, but at the same time noted that there "is a long way to go" yet this season and that it isn't like last season when there was "almost no margin for error".
