Roy Keane fears Man United has not yet reached Rock Bottom, since he says that the club's standard has been falling for years

Roy Keane believes that Manchester United could still reach new minimums after what has been a miserable season.

The Red Devils feel 15º in the Premier League before Sunday's clash with Arsenal.

The arrival of Ruben Amorim has not made the new manager bounced that many could have expected.

'We always talk about giving managers time, but you can't continue losing football matches.

'And I can say that for most clubs, if you are losing week after week, they will be doubts in the locker room.

'The players will look at the manager and thinking “What are you bringing to the party?'

'And when there has been no reaction after coming to the club, that is a bit worrying.

'Club's standards have been falling for several years, and have you reached Rock Bottom? Maybe there is a bit to go still … '

Speaking in an interview with Sky Sports on Sunday, Amorim admitted the challenge of changing things at Old Trafford after several disappointing months under the new manager.

“To tell the truth, I feel that sometimes there are scars on our team, in our players,” said the 40 -year -old specialist.

'They are good players, but they (scars) are so deep that they are so long here that it is difficult to change things in a moment.
