Real Sociedad boss David Moyes has revealed his disappointment after his side dropped two points against Athletic Bilbao on Sunday.

Sociedad took the lead after just three minutes of the La Liga clash, but 10-man Bilbao responded in the second half to secure a share of the spoils in the Basque derby.

"We played well in the first half but didn't maintain it after the break and our energy levels dipped," Moyes told reporters.

"We need to play with the same intensity for the whole 90 minutes, not just for the first 40 or 60, and I told the players that playing as we did before the break we'd have won the game.

"Having said that, I saw an improvement from the last game against Villarreal and we are growing together, but we must be more consistent and correct the small mistakes."

Moyes has won one, drawn two and lost one of his four games in charge of Sociedad.
