West Ham United have reportedly made a double swoop for Bournemouth pair Callum Wilson and Matt Ritchie.
The Cherries have reportedly rejected this initial bid, and it seems that Mostyn would not welcome any future offers from the Hammers.
"First of all, we don’t speculate on any comments regarding our players," he said, when asked about West Ham's bid. "From our perspective we want to keep our players together.
"The last thing we need now [is to lose players]. I’ve got every confidence that we’ll improve. When you have an amazing team bond you do not want to let the squad separate, either in or out."
West Ham co-owner David Sullivan confirmed that his side had made a £25 million bid for a Premier League striker last week, and it seems that the identity of the front man was Wilson.
West Ham have plenty of funds to spend in the summer transfer window, and they are believed to be on the look out for a striker.
Wilson’s first season in the Premier League has been disrupted by injury, but he still showed his class when in Bournemouth’s team.
Wilson netted five goals in his first seven top flight appearances, before picking up a knee injury.
Ritchie, meanwhile, has been fit all season - and he has been one of the most integral players as Bournemouth have avoided relegation.
