We were naive - Monk
Middlesbrough boss Garry Monk accused his players of being "naive" following their 2-1 defeat at Millwall.
Boro trailed to Jed Wallace and George Saville goals before the interval, until Stewart Downing offered them renewed hope midway through the second period.
"We know coming here - we've prepared the players all week - the direct play it's going to be: that battle, that physical element to it," Monk told BBC Sport. "To then be so naive and lose a lot of those battles in that first half in important areas - it's naive, schoolboy stuff.
"I've said it too many times this season. It's never through a lack of effort within the group. It's just comes back to naivety. I feel like a broken record at the moment," he admitted. "And you don't expect that from the level of players we've got, but unfortunately it's happening too many times this season."
