Premier League clubs are at risk of ceding power to European rivals if they shorten the length of the transfer window, according to former player agent Sky Andrew.

Top-flight clubs are due to discuss the proposition of moving the transfer deadline to the start of the season, with the majority of clubs reportedly in favour of the move.

However, Andrew, who has previously represented Sol Campbell and Jermain Defoe, believes the change could see the big European clubs dominate the transfer market.

"Agents are speaking to players and clubs throughout the season, it's not going to change how much work agents do, even if it is shortened," Andrew told Sky Sports News.

"But here's where bigger clubs better look out. If the window closes earlier, ahead of Europe, then the big clubs in Europe can come and take players from our big clubs.

"It's not going to be easy, but the big powers - Barcelona, Real Madrid, Bayern Munich - after the window is shut they can come and start bidding big money for our players.

"How can our big clubs let their big names go? It's going to be a bit of a power struggle, but it is going to put our big clubs at a bit of a disadvantage if clubs come in with big-money offers.

"Fans are not going to want to see their squad depleted and you can't go again until January."
