The gaffer discusses the upcoming pre-season trip
Neil Harris says the training camp in Portugal is "hugely important" to Millwall's pre-season preparations.
The Lions fly out on Thursday afternoon and will take part in three sessions a day as well as a first friendly against a fellow English side.
And the Millwall boss has offered some insight into why he believes the week-long exercise is so crucial as the countdown to the opening day of the season continues.
"It is hugely important," Harris said.
"The opportunity for us to go away somewhere with decent weather and good facilities is key and we're thankful to the board.
"The players will be living together and we can monitor and get to know the players even more in that period of time as a group of staff.
"Three training sessions a day gives me a great opportunity to do some in-depth video analysis with them on our plans for the season and how we're going to play.
"We'll have a game against some English opposition while we're out there behind-closed-doors so that will give the boys a good taster of being back out on the pitch.
"When we get back for the friendlies against Bromley, Dartford and Crawley we will hopefully be in good shape."
He also insists that trip will be especially key for the club's three summer signings.
"We've got a great group of lads and they make the new boys feel welcome," Harris added.
"All three have already moved or are in the process of moving to the area so it will be good for families to meet and socialise.
"For the lads, going to Portugal will be a great time for them. They will have time 24/7 to spend with their team-mates and it is key at this stage of the season that the players bond."
