The Red Devils' new permanent boss struggled to live up to expectations during his last spell as a head coach in the English top flight
Ole Gunnar Solskjaer's appointment at Manchester United came as a surprise to Tommy Smith, who felt the Norwegian had poor man-management skills during his failed stint at Cardiff City.
Smith, a former attacker, was part of the Bluebirds side that finished bottom of the Premier League under Solskjaer's stewardship in 2014, with the Welsh club registering only three wins during his tenure.
Underwhelming results were mirrored by a lack of impact from players brought into the club by Solskjaer at that time, leaving Smith shocked when his former boss was handed one of football's most coveted roles.
