When Ralph was asked about this in yesterday's press conference, he gave a wry smile and acknowledged it wasn't working too well "yet" but he said there are advantages to playing this way once the players have got used to it (or words to that effect). So, it could be something we need to be patient with as fans, if Ralph is convinced it'll pay dividends long term.
Or, of course, in acknowledging it isn't working (at the moment) he may well decide to ditch it sooner rather than later...
