Bielsa managed former United midfielder Herrera during his time at Athletic Bilbao and the current Paris Saint-Germain midfielder put his loyalty to United aside to congratulate his former boss on Twitter.
“MUFC will always be my team in England, but putting rivalries aside I want to congratulate Bielsa and his honest and always attractive football. I’m so happy for you, Marcelo, ”wrote Herrera.
Current United striker Marcus Rashford has also tweeted that he is happy to see Leeds return to the Premier League, but was quick to remove his post following backlash from supporters.
United fans had a different reaction to Herrera’s tweet, filling his responses with requests for him to join the club. The 30-year-old left last summer and some fans believe it was not the right decision to let him go.
Herrera said to Athletic last month he believes United have three players capable of leading a title challenge for United in the future.
“They [Rashford and Martial] have the quality of being among the top 10 in the world, ”he said. But they have to do it for a long time and keep it. It’s the same for Paul [Pogba]. Rashford is on the way to doing it. And Paul can be the best midfielder in the world if he keeps playing those games where we’re all amazed by him.
“But keeping him at this level is the hardest thing in football. To stay there Sunday-Wednesday-Saturday, every time.
“If these three can do it, Manchester United will win the Premier League soon, that’s for sure. “
