Foster confident West Brom will make right signings
Foster has signed permanently from Birmingham City this summer.
He told the WBA website: "I don't know what sort of players we're looking to bring in - that's completely down to the gaffer.
"But I think every player here trusts in the management and board to bring in the right players, so we'll leave that side to them.
"From a playing perspective, we're going to be looking to do as well as, if not better than, what we did last year."
