West Brom boss Ryan Mason felt his side made too many mistakes in the first half at Southampton as they trailed 3-0 at the interval before rallying to 3-2.
The Baggies have lost their last seven Championship away games and Mason feels they must deliver a 90-minute performance.
Mason told BBC Radio WM: "No, it's certainly not the time to do that [launch a comeback] when you're 3-0 down after the first half and the nature of why we were 3-0 down.
"I think the bigger concern, yes, in the second half, how that panned out.
