Pep Guardiola's second season in charge of Manchester City is shaping up to be a lot more successful than the first.After finishing third in the Premier League last term, 15 points behind champions Chelsea, the Spaniard went about making a number of changes to his squad over the summer.Kyle Walker arrived for £50 million, Benjamin Mendy and Bernando Silva both signed from Monaco, while Ederson was brought in to replace Claudio Bravo in goal.And so far, all is going to plan. City are top of the Premier League, unbeaten and have scored 21 goals in seven games.Oh, and they've only conceded twice. So much for a leaky defence.Guardiola's intention has always been to build a squad that mirrors his philosophies at City, much like he did at Barcelona, and it's starting to take shape.One player who threatened to disrupt Guardiola's plans was Sergio Aguero, but even he is now on board."He has always had the character to score goals," Guardiola said of Aguero last week. "His mother and father gave him that talent."He had it before in Argentina and Spain. He will die scoring goals, there is no doubt about that."When I arrived I tried to convince him not just to be a striker who made a connection in the box, but to help win the ball back as quickly as possible, to attack as quickly as possible and be involved in the process to play football."I like strikers who play in the process as well as scoring goals, just as I like my central defenders to be involved in the play and not just defend."Guardiola comes across as intense and stern on the sidelines, but he very much has a fun side, too.In a wide-ranging interview with Gary Lineker on BBC Sport, the former Barcelona boss recalled a hilarious story involving Lineker himself.It turns out that when Lineker was a Barcelona player from 1986-1989, Guardiola was a ball boy at the Camp Nou - how amazing is that?

What's not so amazing is that Guardiola used to ask Lineker for his shirt after games but the Match of the Day presenter never gave him it. Here's what they said:

Guardiola: In your period I was a ball boy and I gave you balls to play in there.

Lineker: I probably didn't control them. I didn't know it was you, as you probably had hair then.

Guardiola: I always asked you for the shirt after the game and you never gave me. Never! I cannot forgive you for that.

Lineker: They never allowed us to give away our shirts in those days. Now they have many shirts but then you had to keep the same shirt all season.
