The build-up to the Baggies' FA Cup fifth-round tie against Southampton last weekend was dominated by the news of four senior players being questioned by police during a trip to Barcelona.
West Brom went on to lose 2-1 against the Saints to end their cup campaign for another season, but this weekend attention turns back to Premier League matters.
"I don't want sympathy from anybody," he told reporters ahead of Saturday's home match against Huddersfield Town. "This is a difficult scenario in terms of the run this club was on before I arrived. And it hasn't improved much since I've been here.
"That's been the one failing at my door and I want to put that right. And I can only put that right now with 11 games to go. That's my challenge individually. As a team and collectively these players have acted impeccably for me.
"This one crazy incident – I won't let it take away from the professionalism and the determination we've shown to try and correct the results. Going forward we're going to have live and die by the margins and hopefully they go our way."
Following this weekend's meeting with Huddersfield, West Brom take on Watford, Leicester City, Bournemouth and Burnley before the end of March.
