Villa's new striker was linked with a move to Everton earlier this summer before a talk with Tim Sherwood convinced him to join the claret and blues.
Ayew, 23, agreed to join Villa this week on a five-year deal from Lorient for around £8.5 million, having netted 12 times in 26 Ligue 1 appearances for the French club last season.
His impressive goalscoring form saw him linked with the likes of Everton [h/t Liverpool Echo] earlier this summer but the Ghana striker claims he was convinced that the claret and blues were the best option for him within 10 seconds of speaking to manager Tim Sherwood.
While not mentioning the clubs in question, Ayew said: “I already wanted to come to the Premier League and had two or three other opportunities but, when I spoke to the manager, within 10 seconds I decided that Aston Villa was the best place for me.
“The Premier League is the biggest league in the world and Aston Villa is a big club in England. I’m the happiest man in the world to be here.”
Ayew, who is the son of Ghana legend Abedi Pele, played just season at Lorient, having joined Les Merlus from League 1 rivals and hometown club Marseille last summer after spending the second half of the 2013-14 campaign on loan at Sochaux.
With most of his appearance coming either off the bench or on the wing, the French-born attacker managed just 22 goals in 147 games during his time at the Stade Vélodrome but, having since had the chance to showcase his potential with regular minutes up top, he believes he is set to make further strides forward at Villa.
“For three years now, every season I’ve improved,” he added. “I’m still young and, like the coach told me, I still have to develop in a lot of aspects.
“The most important thing for me is to keep on developing, to give 200 per cent on the pitch and to make the fans happy.”
At 5ft 11in, Ayew will not be a like-for-like replacement for the recently departed Christian Benteke but, with 28 international caps to his name, World Cup experience and six seasons of French football under his belt, the Black Stars regular arrives at Villa Park with a solid career résumé.
His move will also give him the chance to lock horns again with his older brother and recent Swansea City signing, Andre, having been teammates at Marseille and played against each other in Ligue 1 last term.
With Gabby Agbonlahor, fit-again Libor Kozak and the untested Callum Robinson the only other forwards at Sherwood's disposal, the Villa boss is in desperate need of additional firepower and both his latest recruit and the reportedly soon-to-arrive Emmanuel Adebayor look like they fit the bill.
