JACK Smith said there were no excuses for Millwall's second-half performance in their friendly defeat at Brentford.
The Lions conceded three goals after half-time as they were resoundingly beaten by the League One side on Tuesday night.
Trialists Nicky Shorey, John Paintsil, Lee Croft and Lee Cook all featured but Smith did not feel an unsettled side was a factor in the result.
He said: "We're not used to playing with each other but it's always easy to make excuses when you lose. They're Premier League players and it should be easy to play with them.
"Shorey's played for England, Paintsil's played for Ghana and Cook has played in the Premier League and had big moves. It should be easy for them to slot it. We can't use that as an excuse and we know the performance wasn't good enough.
"These games are to help build up our base fitness and get the rustiness out and blow away the cobwebs. If we beat Yeovil on the first day of the season everyone will forget about pre-season results.
"Obviously you don't want to lose – you want to give the fans something to look forward to, which we probably didn't after Tuesday, but it's still early days."
Utility man Smith is hoping to nail down a single position ahead of the new season, having often been used to plug gaps in the team by former boss Kenny Jackett:
"In training I've been playing right-back, midfield and centre-back," he said. "I haven't spoken to the new manager one-on-one about that but maybe I need to, just to clarify things and see what he thinks.
"We're getting a lot of players in so you want to nail down a position that the manager knows you can play in. Given the squad we're accumulating, it's going to be even tougher to get in the team on August 3."
