I tried to see his last round bets in this league, couldn't get back that far though. If he starts off well with the Sarandi game, i might back his tips in the next 2 games.
Follow his tips for a week and take notes. Don't back anything. See his track record. It was EPL and German Bundesliga he did well in last season.
I remember on a few occasions he tipped a few scorelines of 2-2 etc - basically scorelines you would never choose and they got up!
