Boss to play two sides in Friday's friendly
Millwall boss Ian Holloway expects his side to have to work hard out of possession against Real Mallorca at The Den tonight (7.45pm).
Ollie believes that the Spanish side, who have only recently just dropped out of La Liga after a lengthy stay in the country's top tier, will keep the ball well and thus represent a different challenge to what The Lions have experienced in pre-season so far.
"I'm expecting us to have to chase the ball a little bit which will provide a good indication of our fitness levels," the Millwall manager says in Friday's edition of matchday programme The Lion
"They will be a typical Spanish team, good in possession and able to move the ball around the pitch well.
"Our challenge will be to win it back as quickly as we can to try and hurt them on the counter attack."
Ollie has also revealed his plans for this evening's friendly in terms of the team selection.
"I'm planning on giving the players 45 minutes each, as I did at Dartford and Stevenage," he said. "You can get a chance to see everybody play, including all of our new signings.
"It's a bit unusual actually because the whole squad will have had a proper training session for an hour and a half this morning before playing a half each this evening.
"Psychologically that is a lot more work for them than just a 90-minute match."
A bitesize edition of The Lion is available around the ground tonight for just £1.50.
