MANCHESTER, England (Reuters) - The journey from the bench to the pundit's studio is so quick in the modern game that some could be forgiven for thinking Manchester United had two managers after Sunday's 1-1 draw with Liverpool at Old Trafford.

After Liverpool manager Juergen Klopp criticised United's tactics and said their opening goal should have been ruled out for a foul, he received a response not only from his United counterpart Ole Gunnar Solskjaer but also Jose Mourinho, who was in charge of the club until he was sacked in December last year.
