The former Bolton boss has brought in Joey Barton, David Rozehnal, Mark Viduka and Geremi since replacing Glenn Roeder at St James' Park, with more arrivals expected before the start of the season. Allardyce saw his side run out 2-0 winners over Serie A side Juventus on Sunday, but although a host of academy talent was introduced in the second half of the game - and helped close out an impressive victory against a side which included the likes of Pavel Nedved, David Trezeguet and Vincenzo Iaquinta - he is not ready to rely on those players during the league campaign. He said: "Pre-season friendlies tend to give false hope. Just because we've beaten Juventus and Celtic doesn't mean we'll start the season well. I certainly wouldn't like to start the season with the players who finished the game. "When the whistle blows at 3pm it isn't about pretty little football, it's about the nitty gritty that the Premier League brings. "When the pressure comes on the inexperienced players can fail under that pressure and you need experienced players at the start of the season to cope with that. "We need to get the players who are injured as fit as possible before the start of the season and then look to the market and bring in some more experienced players."
