Tony Pulis saw West Brom kick off the season with a 1-0 win over Crystal Palace and then called on the board to splash the cash.
It was announced last week that a Chinese group led by investor Guochuan Lai had agreed a deal with former chairman Jeremy Peace to buy the club – currently 11/4 with Titanbet to be relegated.
Former Blackburn chairman John Williams has since succeeded Peace, and Pulis has called on him and the Yunyi Guokai (Shanghai) Sports Development Limited group to invest in new players.
On Saturday they were the better team as they won their opening fixture, but the manager is concerned they have “stagnated” and need to strengthen in the coming weeks.
“The club has had, and still has, a lot of players who have been here for a long time,” said Pulis, whose team won thanks to Salomon Rondon’s second-half header.
“They’ve been fantastic players, fantastic servants, but they need competition, they need people who can play in that team and want to be in that team. That’s what this club needs.
“I’ve been here now 22 months. It’s been one of the things I’ve said – the club has almost stagnated, and it really needs to get on its front foot.
“It’s the only club in the West Midlands this year that’s in the Premier League, (has) fantastic support, and the supporters and everybody around the place – we need a little bit of impetus.
“We’re trying to do business, we need to do business, and we’ll go from there. Hopefully we’ll get it in the next two weeks. It’s a big two weeks for me and the football club.”
