If City are to retain the title, they will be relying on Aguero to continue getting among the goals, especially with the pressure mounting going into a crucial stage of the season.
"He has had the possibility to take the best players at Barcelona, in Bayern and in City, little by little".
"I think he's done, with that group of players, really, really well". Secondly, he played at Manchester City with the youth teams. Predominantly a central midfielder, Suarez is also comfortable in more advanced positions and boasts the technical ability to play on both wings.
Benjamin Mendy is another player who is a concern for Guardiola, as reports suggest the Frenchman might still not be close enough to be starting for Man City.
Said Emery, 47: "I have analysed a lot of teams and coaches and I think it's hard to find one coach who is better than Guardiola".
In midfield, Guardiola is now able to call upon Kevin De Bruyne after his return to fitness, and the defeat to Newcastle was the first time this season he's been able to field his first-choice trio of De Bruyne, David Silva and Fernandinho - not that it helped.
He told Sky Sports: "I've never been with him in his clubs but my impression from outside is that he's a manager who is well prepared".
Guardiola recognises the importance of the coming week but expects there to be several more of such intensity before the season ends.
Aguero hit a hat-trick for his side as they hosted Arsenal on Sunday afternoon.
The result leaves Arsenal sixth in the table, three points behind fourth-placed Chelsea.
City's accuracy has dipped this term.
Arsenal comes into this game on the back of a struggling win over Cardiff City in midweek, where a penalty from Pierre-Emerick Aubameyang and an Alexandre Lacazette goal ensured all three points for the side. Their shooting accuracy has also diminished, with 38 per cent of their shots hitting the target rather than 40 per cent.
"There was the discussion this year that people said we should focus only on the league".
"When we win, we always want to analyse the bad things we have done and the good things".
