Millwall's training camp in Portugal began on Saturday with the players undergoing a relatively light opening session in preparation for a behind-closed-doors friendly in the evening.
Boss Neil Harris, alongside his coaching staff, hosted an important video session on the first morning in the Algarve, afterwhich the squad went through some tactical work at their training base.
The opening day's work was designed to build up towards that friendly in the evening, with the players then set for some gruelling sessions back at their training facility throughout Sunday.
