Norwich City goalkeeper Tim Krul is interesting Manchester United.
United are eager to buy experienced cover for No1 David de Gea after sending Dean Henderson on-loan to Nottingham Forest.
The Sun says the Old Trafford vacancy is proving a nightmare to fill with United considering Norwich's Krul, 34, as a No 2 option.
Watford's Austrian international goalkeeper Daniel Bachmann, 28, is also a live alternative.
However, Borussia Monchengladbach's Yann Sommer seems to be the hot choice right now.
