Adam Lallana admits Southampton were "off the pace" in their 3-0 defeat at home to West Brom on Saturday.
Three players were sent off in the contest, two for Saints, as goals from Marc Antoine Fortune, Romelu Lukaku and Shane Long secured a simple victory for the Baggies.
Lallana felt the result reflected West Brom’s dominance despite the dismissals of team-mates Gaston Ramirez and Daniel Fox – Fortune was also sent off for the visitors.
“It was one of those days but you can’t just blame that [the three red cards]," he told the Southern Daily Echo.
“We didn’t play as well as we’ve been playing at home, we didn’t play high enough up the pitch, we didn’t press enough, we didn’t win the ball back high enough up the pitch or pass the ball well enough.
“All those factors combined in this poor performance. If we go through individually we were all off the pace really. That combined showed in the performance and the result."
Stoke’s win over Norwich moves them above Southampton, who drop to 13th, seven points above the relegation zone.
“It was really disappointing because West Brom beat us back at The Hawthorns and we kind of owed them one really," Lallana added.
“It was disappointing that is was so easy for them. We are going to work hard and we have a tough game and we want to get a result at Tottenham.”
