Vipotnik, 24, has been linked with clubs across Europe in the wake of his spectacular 2025-26 campaign, but Swansea have indicated there have been no bids yet for the Slovenia international.
Republic of Ireland player Idah, 25, will be aiming to make a bigger impression in his second year at Swansea having played second fiddle to Vipotnik – and suffered a serious hamstring injury – last term.
The arrival of 30-year-old Stewart, who was a free agent after failing to agree a new deal at Southampton, means there will be fierce competition for a place in Swansea’s attack.
But Matos is adamant the former Sunderland player has not been recruited because one his other forwards is likely to be sold.
“We signed Ross because we believe it was an opportunity for us to catch a player with that right type of profile,” he added.
“It’s nothing related to [Vipotnik] leaving or not. It’s just what was a [good] opportunity.
“He brings leadership in a position where we needed experience of the league. He offers the same spontaneity in terms of the penalty box that Vipi (Vipotnik) has, he offers the same physicality that Adam can offer as well. So I think it’s a good combination with what we have at the moment.”
