Why should I believe ? 9 out of 10 picks from so called "experts" are wrong because they are being paid from bookies to actually give false predictions. It's way better to simply forget that sports experts exist and just focus on your own predictions based on your own calculations and so on.
Even AI predictions at Euro went so wrong like 7 out 10 calls were wrong so no matter who makes the predictions , they always tend to be wrong.

Bookmakers/brokers never pay experts for “wrong” predictions. They simply pay them for information noise and the illusion that there is a way to beat the exchange/bookmaker. Mathematics will do the rest - regardless of whether you place the bet correctly or not, the bookmaker will always beat the crowd and receive their margin.
I am sure that the developers of exchange trading strategies (all sorts of waves, figures of technical analysis and other nonsense) receive money from the industry (exchanges/brokers) as they lure new simpletons into the market with their “strategies”.
