BRENTFORD'S PROCESS for recruiting players is a model for other clubs, according to Neil Harris, as his side get ready to face their London rivals on Friday.
The Bees sold centre-back Chris Mepham to Bournemouth for £12million in January after taking him from Chelsea as a teenager.
Brentford will make a huge profit on Neal Maupay, whom they signed from St Etienne in France for £1.6million in 2017, if they sell him in the summer. The club have put a £15million price tag on the striker.
Thomas Frank's side won't finish in the top six and can't be relegated.
"They've been a little bit inconsistent," Harris said. "They have superb players. In so many ways they are a great model how to build a club and get players in with a very good scouting network.
"They sell players on for a lot of money. We're aware of their players and the press links concerning players that might be sold in the summer.
"It's just another test for us at this level, it's no different to what we face most weeks. It's no different to what we faced against West Brom and the quality of the squad they have, or against QPR, Sheffield United. Every team at this level has ability.
"It's going to be a tough challenge for us but one we'll be prepared for."
Harris has to decide whether to stick with 3-5-2, against Brentford's 3-4-3, or revert to four at the back, the default formation at home.
Harris brought Shane Ferguson straight back into the side after his red card against Brighton in the FA Cup ruled him out for three games.
The Lions boss said at the time that Ferguson would face "severe punishment", but this week highlighted what the Northern Ireland international brings to the side.
"It was out of character, yes," Harris said about the dismissal. "A winning mentality and character? Yes, he certainly has that.
"He's made an error but he's redeemed himself over and over again this season, so it's not a major issue. At this football club I want players who have an edge and a personality. Fergie's certainly got that."
Millwall travel to Villa Park to take on promotion challengers Aston Villa next Monday.
