David Moyes must be wondering whether it is all worth it.
Moyes' stock was high after enjoying an 11-year spell with Everton but failed stints at Manchester United and Spanish club Real Sociedad have turned the Scot into something of a joke figure.
The 53-year-old was handed a lifeline by Sunderland but the early signs are that he will struggle to convince many he can still manage at the top level.
After narrowly losing his first game at Manchester City last week, Moyes saw his side go into half-time at the Stadium of Light 2-0 down to Premier League new boys Middlesbrough.
And Twitter was quick to get stuck into Sir Alex Ferguson's 'Chosen One'.

David Moyes's player knowledge is truly awful. Literally only knows the English market & even that's limited always buying ex players.

David Moyes succeeded Sir Alex Ferguson. David. Moyes.

An acrimonious exit from United. An uninspiring spell at Real Sociedad. Now being booed by Sunderland. When will David Moyes find bottom?

Definitely beginning to think David Moyes' ideas are slightly outdated- they've been so negative and reactive today so far.

Not surprisingly, this definitely looks like a David Moyes team already. Defensive lapses, confused attack, and no fight after going down.

I can't believe Moyes gave us actual money for Donald Love. Sunderland would be better off with Donald Trump at Right Back.

You don't need to understand Spanish to know this is not kind.

Patrick van Aanholt gave Moyes hope of escaping with a point but Cristhian Stuani's double ensured it was a miserable first home outing for the new Black Cats boss.
