Herrera left Manchester United last summer.
He told ESPN: "I will always have a bit of United in my heart and I wish them the best because the fans were amazing with me.
"I will never be able to give all this love back, but I wish them all the best, of course. I enjoyed five amazing years in Manchester.
"I have the best memories about the club, and I will never be able to give back all the love and affection that they gave to me in the last few years.
"I haven't won a league title since I was a professional, because in Manchester we had the possibility to win some trophies but not the Premier League, so I was looking forward to it, but we couldn't do it on the pitch."
