Onana was left out of United's clash with Arsenal last time out despite not being injured but Bayindir, who was the Cameroon international's number two last season, didn't cover himself in glory when called upon. That has, seemingly, led to links with Antwerp keeper Senne Lammens, who, if signed, could dislodge both stoppers at Old Trafford. It remains to be seen who will be the Red Devils' first-choice keeper when the end of the transfer window rolls around in just over a week.
