After Jose Mourinho was dismissed in December, United’s executive vice-chairman Ed Woodward decided to give Solskjaer a contract until the end of the campaign.
But the Norwegian hit the ground running at Old Trafford by winning his first eight games, while he also guided United to a remarkable comeback victory against Paris Saint-Germain in the Champions League.
However, since that 3-1 victory in Paris on March 6, United won just two matches and lost eight of their remaining 12 games in all competitions.
Solskjaer was given a three-year contract at the end of March and is now tasked with a major rebuild of his United squad, who will play in the Europa League next season.
Ferguson feels that United should have made an attempt to lure Pochettino away from Tottenham, before Solskjaer was given a permanent contract.
The Scot is understood to be a huge admirer of the 47-year-old, who has guided Spurs to the Champions League final this season.
Ferguson is also, “disappointed” that he has been marginalised by Woodward and is forced to keep up to date with the team’s plans via Solskjaer’s assistant Mike Phelan, who worked alongside the Scot during his time.
