Borussia Monchengladbach goalkeeper Yann Sommer has welcomed interest from Manchester United.
United see the Swiss as cover for No1 David de Gea.
United had scouts posted to see Sommer against Hertha Berlin on Friday and he said: "I keep saying it: We are in very open talks with the club, in general no stress.
"I've been here for a long time and we've done a lot of nice things.
"I've always said: As long as I play here, I'll give everything for this club."
