When new managers are appointed at a big club, they usually have to make one or two massive decisions almost immediately.
For Jose Mourinho at Manchester United, he decided to bring in Rui Faria as his assistant manager, ultimately ending Ryan Giggs’ 29-year association with the club.
And, this weekend, Pep Guardiola made the first big decision of his own after being appointed as Manchester City boss.

That was, of course, picking Willy Caballero as his goalkeeper over Joe Hart.
Hart, who has been at Manchester City since 2006, was made to watch from the substitutes bench as Guardiola's era at City got off to a winning start after overcoming Sunderland 2-1 at the Etihad.

But, like all players, Guardiola believes that the England goalkeeper is far from satisfied from being dropped for the starting line-up.
"I'm pretty sure he is not happy," said Guardiola, per Sky Sports.
"All the players who don't play aren't sacked, they're absent. Of course, I would not be happy if absent, but now it is 'try again'.
"I am sorry, I have to decide (on the team). We have 28 players. They have to convince me on the pitch."
Hart has played 347 times for the Citizens since joining from Shrewsbury and has been instrumental in helped the club win two Premier League titles and an FA Cup in recent years.
However, question marks have recently been raised regarding the performances of the 29-year-old - especially after a couple of high-profile mistakes for England at Euro 2016.
The reason why
And Guardiola has revealed exactly why he preferred Caballero on Saturday.
"Maybe the next game it changes, maybe not. I needed the build-up and to use the goalkeeper to play quicker to arrive the balls behind the line. Willy had this quality first of all, he trained more times. He arrived on the first day,” he said.
"That doesn't mean Joe can't do that. I know the quality of Joe, he is an amazing goalkeeper. He plays for the national team and he was so important for the two Premier League (title) wins. The personality, the character, I know about."
It's certainly difficult to imagine Hart being satisfied to sit on the bench for City for the entire season and there is bound to be plenty of clubs around Europe keen to sign a quality goalkeeper. With just two weeks remaining until the transfer window slams shut, it's going to be interesting to see where Hart's future lies.
