He wants a competent board who have a clear strategy and know how to invest. From his interview:
“I always said I wanted to end here and I always said I wanted to stay here. That I wanted a winning project and to win titles with the club, to continue expanding the legend of Barcelona.
"The truth is that there has been no project or anything for a long time, they juggle and cover holes as things go by."
Barca have spent close to 1B euros in the last 5 years since they won the champions league in 2015.
Andre Gomes, Alcacer, Neto, Alexis Vidal, Digne, Delafou, Mina cost a 180 mill alone. Spent 110 mill on Dembele who although is extremely talented, he hasn't the mentality to become a top player. Only 130 mill of the 1B they spent in the last 5 years started against Bayern.
There's also the Barcagate debacle where the board hired I3 Ventures to boost their image and negatively portray club legends and current players who were slating the board. That deal is also currently being investigated for possible corruption.
