Borussia Monchengladbach goalkeeper Yann Sommer is flattered by Manchester United's interest.
Erik ten Hag wants cover and competition for David De Gea after his poor performance in the 4-0 loss to Brentford last weekend.
There are question marks over De Gea's ability to play out from the back, which is a key aspect of ten Hag's playing style.
According to Sky Germany, Sommer is 'very flattered' about interest from the Old Trafford club.
However, the Switzerland international does not want to risk his spot in the national team for this year's World Cup.
This means Sommer wants reservations over playing time before making the move, given compatriot Gregor Kobel impressing for Dortmund.
