PRESTON North End manager David Moyes is ruing the influx of foreigners into the British game -- but accepts it's part and parcel of modern day football.

North End, like Blackburn, Burnley and Bolton have been inundated with triallists from abroad who have turned out for their reserve sides.

In fact, Wanderers boss Sam Allardyce said he'd seen around 50 come and go so far this season -- but only found two he decided to keep.

"I think the market is abroad now. I would love to say that is not the case but the general practise is to look abroad because of prices," said the Preston boss. Some British players look for far bigger wages than foreign lads and the Bosman ruling means more players are coming in.

"I think if you look at every club in Britain, they will have at least one triallist at the club. I couldn't say how many triallists we've had this season."

Moyes has said agents are continually ringing up -- especially after Preston's Second Division Championship win last season and their great start to life in Division One.

"It is exciting times for us and we are all trying to progress.

"It is easy to attract people to your side when you are doing well.

"Agents are on the phone all the time, telling me they have the best players in the world.

"I like to see them in action myself. They come and go now and it has become a big part of football." Preston made some swift purchases three years ago which has limited the need for imports.

Defender Colin Murdock, midfielder Michael Appleton and striker Jon Macken -- who has just signed a new four year deal -- were all snapped up from Manchester United in 1997 within a few months of each other.

While they were all not first team regulars straight away, the trio have certainly made an impact now.

"We took Jon, Michael and Colin, £500,000 for one and a couple of hundred thousand for the others, three years ago.

"When you look back now it's very small money but it was an awful lot of money then. What would that money be now? You cannot always get it right and it has taken around three years.

"It is an important balance, those that will certainly play in the side and those for the future."

But Preston do also boast a youth policy which has brought two of this season's regular players, winger Paul McKenna and goalkeeper David Lucas, through the ranks.

"It is difficult to give youngsters a chance as last year we were top of the league and desperate to win games to keep it going so you do not take as many risks with youngsters," admitted Moyes.
