Giggs & Nani
Ryan Giggs is a legend, possibly the best player United have ever had. This, however, may be his last season.
He can still produce moments of magic, such as the last minute goal against Norwich last season, but he is in danger of becoming a liability.
In the first half against Spurs and in the ten minutes or so on Sunday, he was pretty anonymous. He can still produce the occasional burst, but he also gives the ball away far too much.
He has solid defensive skills for an attacking midfield, but that's not too much use when he's stranded upfield.
Which has become Evra's problem. It was acutely obvious in the 6-1 thrashing by City last season. It was also the case against Stoke, for the Kightly goal.
Nani, sadly has become a shadow of his former self. Ever since he demanded a near 50% increase in his wage for a new contract, his star has been waning. He now seems to believe he's not wanted.
Frustrated by Nani's unrealistic demands, Sir Alex allowed Zenit St Petersburg to talk to him. He didn't want to go there. He doesn't want to leave.
But all this has affected his form. He's far less effective. When he plays he also loses the ball far too much.
In summary, Manchester United thrive on possession; they play best in a 4-4-2 formation; they dominate matches by playing a high line. They can sustain that line against counter-attack by having pace in midfield and defence.
The times and the tactics are changing. Football at the highest level is faster paced. It's based on close passing, high technical skill and positional interchange. It relies on winning the ball back as quickly as possible when it's lost. Seven seconds is Brendan Rodgers' mantra.
United conceding goals is not really the fault of any of these players. Sir Alex wants to move on. He's been hampered by another injury crisis in defence. He doesn't want to take risks with young players until United are playing from a position of strength again.
Bill Shankly believed that as long as you scored more goals than the opposition that was OK. By and large United are managing to do that, but they've been living by the skin of their teeth.
At the start of the season Sir Alex swore that United would never lose the title on goal difference again. As soon as he has a full and fit squad we may see these defensive problems melt away.
