Ole Gunnar Solskjaer has taken over as Manchester United's caretaker manager until the end of the season after the club dismissed Jose Mourinho.
Solskjaer had an uncanny knack of bailing United out of trouble as a player and Sir Alex Ferguson would regularly summon the striker from the bench if his side needed a goal.
The Norwegian's super-sub status won him the nickname the 'Baby-Faced Assassin' due to his youthful looks and killer instincts in the box.
Here, Press Association Sport looks at some other memorable footballer nicknames.
