Mark Hughes has confirmed Stoke City have made several bids for West Brom striker Saido Berahino.
Hughes also refused to be drawn into commenting on speculation that Stoke could be interested in signing former Arsenal and Manchester United striker Robin van Persie from Turkish club Fenerbahce.
Sky sources understand a bid of £20m has been made for Berahino, who has one year remaining on his current contract with the Baggies but turned down the offer of a new four-year deal last week.
"We've put some bids in and as it stands those haven't been accepted yet," Hughes told Sky Sports News HQ. "But we're still hopeful on them."
Last summer, Berahino threatened to "never play [for] Peace" again after a move to Tottenham broke down.
Berahino started as West Brom lost 2-1 to French champions Paris Saint-Germain on Wednesday in their final pre-season game of their tour of Austria and then scored two goals in a friendly against Kidderminster on Saturday.
Van Persie scored 16 times for Fenerbahce last season but has been linked to several Premier League clubs.
Hughes said: "We've seen the speculation and there are going to be a lot of those stories. Some will have a little bit of substance and some won't.
"We're looking to address key areas in the team that we feel we can improve on and if those players become available, then we're interested."
