They need to get rid of Beglin altogether. He's a horrible co-commentator IRL. His overuse of the words 'just', 'might' and 'possibly' are infuriating. Can't really stand Jon Champion either. Heck, listening to Peter Brackley alone on PES 5 was better than them two.
This idea that you need two guys as a team commentating on the game is silly anyway. Barry Davies never needed that, and he's the best English commentator of the past 20 years at least by miles, his commentary in Actua Soccer was great (I remember when you would try and cheat and move with the player forward a few too many steps when taking a throw-in, he'd say something like,"Hold on a minute, you can't do that!").
They should get a few commentators to do solo commentary jobs. The guy who does the lesser UCL games on ITV has a better commentating voice than Champion, and he should be given a try. You could try Jonathan Wilson (I think that's his name) from BBC MOTD or the guy who used to commentate on Eurosport but now does Serie A games on ESPN and Athletics on BBC.
EDIT: Oh, and reviewers who keep on mentioning that Konami are missing licences should be banned from reviewing PES again. It's always been that way. It's not Konami's fault they don't have an endless pit of cash to monopolise the licences.
