IAN Holloway will not start with his strongest XI against Real Mallorca tonight.
Instead, the Millwall boss will give each of his players 45 minutes to demonstrate that they deserve to start against Leeds United in the Championship opener.
Holloway does not want to give the Yorkshire side any clues as to how the Lions will line up at The Den on August 9.
"I'm going to keep my cards very close to my chest," he said. "If Leeds come to watch us, they won't have a clue who is going to start the following week.
"We'll train on Friday morning for an hour-and-a-half and the lads will play 45 minutes each in the evening.
"We've played 90-minute games behind-closed-doors and I don't think Leeds were allowed to watch those!
"Everyone will get a chance to chase the ball against a Spanish side and do a bit more running.
"We're training before the game so it will be like a full-time job for them – it's about time some of these boys did that!"
