"It is difficult to say now who will play in Eindhoven, but it is clear that we will be making several changes," said the boss.
"But we will probably take most of the senior players because of the prospect of injuries.
"The players are involved in more matches these days. Kuyt, Carragher and Arbeloa have all played a lot of games this season.
"But we have to send out a squad with four local players because of the regulations, so that does not make it easy.
"We cannot obviously, use young players who are not on the list registered for the tournament, so we are limited in making many changes.
"But Lucas will be involved. People have criticised him recently but he has been working so hard, he is the kind of player with a great character who will become very important for us."
