The Red Devils are on course to finish second in the Premier League, while they’re through to the quarter-finals of the FA Cup and last-16 of the Europa League.
Solskjaer’s side have recovered from a terrible start in the Premier League, losing two of their first three matches.
The second of those was a humiliating 6-1 defeat to Tottenham at Old Trafford in October and the manner of that defeat has had a scarring effect on United’s games against their top-six rivals this term.
Until the 2-0 win against Manchester City earlier this month, United had managed just one goal in the seven fixtures against their rivals as Solskjaer often deployed Scott McTominay and Fred in front of his defence to give them further protection.
While that has resulted in plenty of clean sheets, United’s attack has suffered and Ferdinand has revealed Solskjaer’s decision to play with two defensive midfielders ‘kills his soul’.
With United it’s the two holders that kill me,’ Ferdinand told the FIVE YouTube channel.
‘When you play two players that hold it hurts my soul. I think that’s Ole’s concern [conceding goals], that’s his biggest concern.
‘Can he leave Harry Maguire or Victor Lindelof on the halfway line one-on-one? It’s been shown, it’s proven you can’t. That’s not their main attributes.
‘Harry Maguire is good at a lot of other things but that area is one of his weak points.’
However, Solskjaer hopes to be able to call on Paul Pogba and Donny van de Beek for the trip to the San Siro on Sunday, giving him more attacking options.
Edinson Cavani returned to training today, while Anthony Martial is also expected to be fit.
