Pep Guardiola at Man City: Toure & Silva out, Messi & Pogba in?

There is no chance that Manchester City's season will be affected adversely just because everyone knows Pep Guardiola is on his way.

Guardiola does not take charge of City until July but he will watch every game they play between now and the summer.

So none of their players can take their foot off the gas, despite knowing that Manuel Pellegrini won't be in charge for much longer. They are playing for their futures.

Yaya 'is not going to be in a City shirt next season'

Toure, who turns 33 in May, won his second Premier League title under Manuel Pellegrini in 2014

I am not sure that even David Silva fits into the template of speed and tenacity that Guardiola's pressing style requires.

But the one player it is definitely not going to suit is Yaya Toure. He is not going to be in a City shirt at the beginning of next season, that is for sure.

Yaya's performances have not been up to the level we expect for a while now, and Pep also got rid of him when he was at Barcelona, which does not bode well.

When you look at the engine room of City's midfield, I would say only Fernandinho has both the ability and physical capability that fit the profile of how Guardiola wants to play.

Fernando and Fabian Delph are both athletic but do not have the quality of, say, Thiago in terms of footwork and ability to dictate play.

Looking at Guardiola's Barca and Bayern teams, he has always liked a proper ball player in that area of central midfield. Yaya does not fit the bill with his fitness levels, so I think that is the first area that the new manager will look at strengthening.

Left-back is another. There is far more to Guardiola's philosophy than just a formation. The full-backs are key to how his sides attack.

Neither of City's left-backs, Aleksandar Kolarov or Gael Clichy, strike me as Pep's kind of players because I am not sure they are good enough footballers to do what he will ask of them.

But for most of the players already at City, it will be a case of wait and see.

I think Guardiola will be excited about working with a lot of them, especially Sergio Aguero, Kevin de Bruyne and Raheem Sterling.

City have quality in most positions so it would be a case of tweaking the squad to suit Guardiola, rather than initiating an overhaul.

'No other club could tempt Messi apart from City'

Lionel Messi, 28, has spent his entire career at Barcelona, where he played under Pep Guardiola from 2008 to 2012

Guardiola also has an impressive record of developing young players but that is probably the last thing on the minds of City fans at the moment.

There is a buzz regarding the players Guardiola can attract. That will continue until the start of next season, at least.

The thought of this City side with one or two world-class additions and Pep in charge is scary for the rest of the Premier League.

Who will come in? Everyone from Juventus midfielder Paul Pogba to Bayern forward Robert Lewandowski has been linked already, and people are also getting excited about the possibility of Lionel Messi coming to the Premier League.

From a footballing perspective, I understand when people say there is no chance of Messi moving. With Luis Suarez and Neymar alongside him at Barca, he is playing for the best team in the world, breaking records and winning stacks of trophies.

But you never know, because you cannot be sure where a player's head is. I have been reading about some of the tax issues he has been facing in Spain and he might just say: "I have had enough."

City would have to pay huge money to get him, of course, but if he wants to go, he will go. All he has to do is dig in his heels.

Messi could stop the speculation, of course. He could say that he has spoken to Pep and wished him all the best, and reassure the Barca fans he is staying.

Until that happens, the stories are not going to stop. City are the only club who could get him to leave, because the only man who could tempt him away is Guardiola.
