Ollie takes eight rookies to Algarve
Four senior members of Millwall's first team squad have not made the trip to Portugal, giving boss Ian Holloway the chance to assess some young players at close quarters.
Ollie explained: "David Forde, Danny Shittu, Paul Robinson and Carlos Edwards are not out here with us. I know all about them, they are our four most senior players, and what I want to do at this stage is find out more about some of our youngsters.
We've brought the likes of Fred Onyedinma, Jack Powell, Josh Siafa and Aiden O'Brien with us to see what they can do and so they can learn what is required of them if they are going to be part of what we're trying to achieve this season.
I do want to integrate a number of younger players into the group, and the eight we have brought out here with us have the first chance to show their worth."
