Sevilla coach Diego Alonso was left frustrated after their 1-1 draw with Celta Vigo.
A late Youssef En-Nesyri goal canceled out Carl Starfelt's opener for Celta. Renato Tapia was sent off on 65 minutes for hosts Celta.
Alonso later said, "I didn't like the first half at all, it was the worst since I've been here as coach.
"The team didn't play well, we improved in the second, we generated more, having more dominance. The field was bad, there was wind, it was complicated. We were at a disadvantage, an organised rival but in the second half we had options to turn it around and the rival also to score because we opened up and we had to take the risk.
"I'll stick with the taste of a first half that was not good and that we have to improve.
"We have to work on and improve, but the glass is half full or half empty. As a visitor, the team has been able to overcome adverse results and go for the game. There are positive things and others that are not.
"We have to rescue some and work on others."
