NEIL Harris believes there will be a "hostile" atmosphere when Millwall face London rivals QPR at The Den on Friday night in their last fixture of 2017.
The game will have added spice as Ian Holloway returns to the stadium for the first time in charge of an opposition side following his difficult spell as boss of the Lions.
Holloway was the manager in charge when Millwall avoided relegation from the Championship in 2014, but he was sacked in March 2015 with the side eight points from safety.
Harris took over but was left with too much to do to steer the team away from danger, before he rebuilt the squad and won promotion back to the Championship last season.
After QPR came from two goals down to draw 2-2 with Millwall at Loftus Road in September, Holloway said: "I kept them up once and they chose to sack me, and Neil was in charge when they went down."
But rather than give his opinion on those comments after the Boxing Day 2-2 draw with Wolves, Harris instead preferred to focus on his side continuing their good run of form at the end of one of the best years in the club's recent history.
"The fans are looking forward to Friday – I think we're almost sold out," Harris said. "That goes to show how excited we are for it.
"The atmosphere will certainly be electric, it'll be hostile. I think that's because it's a London derby, first and foremost, against QPR.
"It's two teams in a similar position and what a great one for the players to be involved in.
"We'd an excellent performance at Derby for 84 minutes, shame about the six in between that cost us three goals.
"We had an excellent performance to compete with Wolves and we take that into QPR.
"The boys, throughout December, have had great spirit among the group, they're buzzing. We're looking forward to it."
