Johansson, 27, has been one of the standout performers in the Championship over the past two seasons, keeping eight clean sheets from 25 starts last campaign as Stoke finished 17th.
A shoulder injury ruled him out for the final weeks of the season but the club nonetheless triggered the option in his deal, tying him down until the summer of 2030.
The Swedish international has also earned a place in Sweden's World Cup squad and started both of their opening group matches.
Aston Villa's interest would represent a significant step up in class. The Birmingham club are in the Champions League next season and carry ambitions well beyond what a goalkeeper at Stoke's level would typically attract. Ipswich and Hull are recently promoted sides with strong knowledge of Johansson's Championship pedigree — both have competed in the second tier during his time at Stoke.
Whether Stoke would entertain offers for a goalkeeper they have just extended on a long contract is unclear. His new deal runs to 2030, giving the club a strong negotiating position. The asking price and the goalkeeper's own appetite for a move will determine whether any of the three clubs makes a formal approach.
Johansson joined Stoke after impressing in a loan spell at Rotherham United in League One. He has quietly become one of the best goalkeepers outside the top flight in England, and his World Cup involvement with Sweden has widened his profile considerably.
For a goalkeeper of his age and profile, this summer represents a meaningful window. The combination of World Cup exposure and reported Premier League interest rarely arrives at the same time. If a club meets Stoke's valuation, this is the moment he is most likely to move.
