Millwall have signed 19-year-old Chelsea midfielder George Saville on a youth loan until the end of the season.
Saville, who can also play in defence, has progressed through the ranks at Stamford Bridge since moving to the club as an 11-year-old from Reading.
He signed professional terms with Chelsea in 2010 and has since featured in their U21 development side this season and has also played for England U16s.
Saville has been given permission to feature for Millwall in the FA Cup.
Burnett this week took charge until the end of the season following Still's decision to end his nine-year reign and take up the managerial vacancy at non-league Luton.
And he watched the Daggers pick up a creditable point at Valley Parade on Wednesday against a Bradford side fresh from their Capital One Cup final hammering at the hands of Swansea.
It could have been all three but for James Hanson's late equaliser which cancelled out Luke Howell's 69th-minute goal, coming after Sam Williams had missed a penalty
Burnett said: "Bradford had large chunks of the game and probably the better chances but we defended excellently. Our two centre-backs and full-backs were fantastic.
"This is not an easy place to come. I am delighted with the performance and the players' work-rate. It's difficult when a manager leaves, especially someone like John Still who has left a legacy at this club.
"I said 'let's carry that on, nothing needs to change. Let's go out and express ourselves, try to be creative and play with no fear'. At times we did just that."
