Here are the Leeds United morning headlines on Wednesday December 30th.
Leeds wait on Klich fitness
On a night where almost everything went right on the pitch at The Hawthorns for Leeds United, there was one moment of concern as midfielder Mateusz Klich went down injured before the hour mark and had to be substituted.
Following the 5-0 win Bielsa confirmed that Klich suffered a thigh problem, but it was too early to say how long he may be out for.
"He received a knock to his thigh and this didn't allow him to continue, but this hasn't been evaluated just yet," Bielsa confirmed.
The Pole, who assisted Rodrigo's goal shortly before half-time that put the Whites 4-0 up before the break, was replaced by Jamie Shackleton.
Leeds face Tottenham in their next Premier League match on Saturday, which is then followed by a two-week break in Premier League fixtures, with the FA Cup trip to Crawley coming after the Spurs trip.
Klich has only missed one league match since Bielsa took over at Leeds two-and-a-half years ago, which was the dead rubber at Derby County at the end of last season.
Allardyce's verdict
West Brom boss Sam Allardyce said he was stunned by his side's performance as they slumped to a 5-0 defeat at home to Leeds United.
A comical own goal from Romaine Sawyers was followed first-half strikes from Gjanni Alioski, Jack Harrison and Rodrigo, before Raphinha completed the rout in the second half.
Coming two days after his side earned a point at champions Liverpool, Allardyce was at a loss to explain the thrashing.
"When we appear to play the bigger sides, not that Leeds are not a good side, but we defended well against Liverpool.
"Here when we try and open ourselves up we can't do the defending right.
"Leeds ended up with a 5-0 win and deservedly so. I was shocked to see a poor performance like that from us.
"Because we defended well at Liverpool and for long period we were better but we were terrible as we tried to open ourselves up."

Moments missed
Beren Cross has taken his usual behind-the-scenes look at last night's match which you can read here.
Luke Ayling's leadership qualities were on display at The Hawthorns, Mateusz Klich was in the thick of the action, while Marcelo Bielsa had a lengthy post-match conversation with Baggies assistant Sammy Lee.
The win means Leeds end 2020 11th in the Premier League table, three points off the European places, but perhaps more importantly in a season where the first priority is maintaining their hard-earned place back in the top flight, 12 points clear of the relegation zone.
