However, prior to the relegation six-pointer between Southampton and Swansea, there was, according to the Daily Mail, some degree of untoward mischief suspected by the south coast club as they prepared for the game.
The Welshman had been handed the task of rescuing the Saints from the threat of relegation when he was appointed in March and was a unusual choice in many people's eyes, having left his former team in a similar predicament.
Manolo Gabbiadini came off the bench to score the all important goal 18 minutes from time.
Either the club, or a Southampton fan, has left a review on the Swansea Marriott Hotel, and the club have posted it to their Twitter page.
The Baggies - now on 31 points from their 37 games - had hoped to reach the final day and repeat their memorable escape of the 2004-05 season. This situation draws parallels with a club in Germany two seasons ago when Hoffenheim were in a similarly desperate position to the one West Brom found themselves in, albeit earlier in the season.
Having been bottom of the table and five points from safety when Carvalhal succeeded the sacked Paul Clement, five wins in nine games took Swansea to the heady heights of 13th place. Their only hope is for a win at home and losses from Southampton (host Man City) and Huddersfield (host Arsenal).
Southampton's win doesn't put them out of the woods yet.
Swansea have scored less goals than any other team in the league at just 27 meaning a big return like that isn't hugely likely - something which works in Southampton's favour.
Former Wales striker Iwan Roberts said the decision on Carvalhal's future was "crucial" to Swansea's future as they plan for life in the Championship after seven successive campaigns in the Premier League.
Were that to happen, they would finish above the Terriers on goal difference.
It's all shaping up for a dramatic final day.
