Reading manager Steve Coppell has admitted that the growing number of his players receiving international call-ups is beginning to concern him.
Ten of Coppell's key squad members will be representing their national sides in coming weeks, and the manager admits that with long distances for his players to cover in their travels, they may not be up-to-scratch for their following Premier League games.
"It is the first time we have had double figures away," he revealed.
"It is an indication of our progress but a worrying time for me because we are going to depend on them on the Saturday afterwards.
"Nicky Shorey is the only one not travelling, and that is demanding. The time difference, that's a big thing."
Shorey's England effect
Shorey has attracted interest in pre-season from a host of Premier League sides, and Coppell admits that his experiences with the national side have wetted his appetite for playing at a higher standard.
The England defender rejected the offer of a new deal at The Madejski Stadium in recent weeks, and Coppell says it can only be expected for his mind to wander to a new challenge.
"England has affected Nicky in two ways," he continued.
"It has added to his confidence - but also he has rubbed shoulders with the big boys, and I am sure it has made him think in the summer. The conclusion he has obviously come to is that he would like to be a bit more free."
