Williams’s managerial CV includes spells at Swindon Town and Notts County with time as Russell Martin’s assistant at MK Dons and Swansea in between.
His last job was as manager at Swansea where he was in charge from January 2024 to February 2025 before leaving the club after seven defeats in nine Championship matches.
“I think now I’m only left to tick off the Premier League at some point and then I’ve done every division,” he said.
“I’ve learned so many things along the way and hopefully those experiences help me in this one.
“I think that there’s some really talented players in there and I think we saw today in training that there’s a belief and a good attitude towards the work.
“We need to try to have the fittest, strongest team that we can have and get the right combination on the pitch together and find the rhythm and the winning mentality.”
His first game in the dugout is against Cardiff City in the FA Cup 1st round on Saturday.
“Of course a victory would be sweeter for me because of the connection with the Swans’ fans but we’ll see because we know it’s going to be a very tough game,” he added.
