Betis were thumped 4-1 by Chelsea on Thursday night, with their bitter rivals Sevilla posting a congratulations to Blues manager and their former midfielder, Enzo Maresca.
Sevilla's post read: "Congratulations to our beloved Enzo Maresca on his first European title as a manager."
We're in different worlds
In response, Haro took a thinly-veiled swipe at Sevilla for their post.
He said on Partidazo de Cope, "I haven't seen it, but they're currently in a different war that doesn't interest me. We're focused on growth, on doing well next year, and they're in a very different war than ours."
"Would Betis have done that?" he was asked.
"Well, if it were up to me, no, but well, I don't know, if there's someone in the organization who does it, well, I wouldn't like it. But anyway, as I said, I haven't seen it, nor do I know exactly what they posted. Is it an official club tweet?"
Haro wanted to know. And when it was confirmed that it had indeed been from Sevilla, he replied: "Well, I also congratulate Sevilla for staying in the Primera Division this year."
