West Bromwich Albion boss Alan Irvine believes some of his players passed up an opportunity to impress in their League Cup defeat at Bournemouth.
The Baggies levelled late in the game against their Championship opponents, but conceded instantly to lose 2-1.
"It was an opportunity for a number of our players who have been desperate for a game to show me they should be in contention," said Irvine, who defended his decision to make 10 changes.
"Some did, but not enough of them."
Irvine's side appeared to have turned a corner going into the last-16 meeting, with just one defeat in six.
Like his opposite number Eddie Howe, the Baggies manager almost entirely revamped his weekend XI, resting top scorer Saido Berahino among others.

The result was a timid West Brom display, with Tommy Elphick's own goal only enough to keep them level for a minute before Callum Wilson won the match with four minutes remaining.
"It wasn't a team of kids - it was a team that, if played to the best of their ability, should have got a result," added Irvine.
"But I'm not hanging any players out to dry. Not enough played well and there are a number capable of better. Some players did themselves a favour, some didn't."
Irvine, whose side fell behind on 49 minutes to Eunan O'Kane's first goal of the season, had a strong penalty appeal with the score at 1-0 when Elphick handled.
They rallied late on but ran out of time as the Cherries reached the last eight for the first time in their history.
"Whilst we were always in the game, we didn't use the ball as well as we could have used it," added the West Brom boss. "We just needed to be better."
