Spanish newspaper Marca (h/t Aaron Flanagan of the Mirror) quoted the popular player discussing the idea of moving to South America, after he revealed he is a long-term fan of the Buenos Aires club.
"Yes, I love Boca," Herrera explained. "Since childhood, when my father brought players from there [for Real Zaragoza]. If one day I get the chance to play in South America, I’d love to go to Boca, the biggest. But it is an idea, eh? I’m focused on my team."
Herrera's father is technical director at Real Zaragoza, and he has recruited players from the Bombonera club that produced Carlos Tevez and have a famous association with football icon Diego Maradona.
The United player also admitted he desires a return to his father's club—the team he began his youth career with in 2004. Herrera said he would like to represent Zaragoza before his latter years, per Marca.
“I see myself playing there [Zaragoza] again, but not when physically worn," Herrera said. "I will return to contribute, not drag back.”
Herrera played 86 times for Los Blanquillos, according to Flanagan, before securing a move to Athletic Bilbao in 2011.
The player also spoke candidly about the arrival of Pep Guardiola at Manchester City, calling the manager "a phenomenon," and saying his arrival will motivate United to improve, per Marca (h/t Alice Piper of Sky Sports):
I'm looking at it from a positive point of view. They're going to make us do better ourselves. Historically, City have always been below United, and this gives them a psychological advantage, because they are coming from behind.
With Pep, with the multi-million pound outlay they've made and will spend with him, I expect the pressure to be higher for them. The fans are going to expect a lot, that they win the Premier League with a 10-point gap, that they reach the [UEFA] Champions League final.
Pep seems a phenomenon to me. His teams always entertain me a lot, but at City the expectations will be very big.
Herrera has failed to grab a regular starting berth since arriving from Athletic Club, as manager Louis van Gaal opts for a pragmatic core at the heart of his midfield.
Despite being left on the bench on many occasions, Herrera said it would be "unfair" to sack the Dutchman at present, per Marca (h/t Piper).
"The way of working in England is to give confidence and we still have the chance of winning three titles, FA Cup, Europa League and Premier League, even though we are 10 points from Leicester," said the Spaniard. "Distances are less here."
However, the player commented on the playing style of Jose Mourinho, a potential candidate to succeed Van Gaal—according to the Manchester Evening News' Samuel Luckhurst—declaring the manager's teams play good football:
While Van Gaal picks the team at Old Trafford, it is unlikely Herrera will be given the chances to become an automatic starter.
However, if Mourinho finds his way to the Theatre of Dreams, Herrera's work rate and flair could be utilised in the self-proclaimed Special One's favoured formations.
But for the rest of the campaign, the Spaniard will have to take his bit-part chances from the subs bench.
