The Slovenian completed his move from Austrian side Sturm Graz this week, and the 46-year-old replaces Neil Redfearn in the dugout, despite the caretaker manager doing a great job since the sacking of Dave Hockaday in August.
Milanic will be hoping to kick off his reign at Leeds with a win against a Brentford side who have conceded seven goals in their last two games. Mark Warburton's side will be desperate to land a victory after a tough week, and they have three players in particular who can hurt Leeds this weekend.
The pacey winger starred for Leyton Orient last season, scoring 12 goals as the O's made the playoff final - a game in which Odubajo hit a stunning volley to put his side in front. His exploits at the Matchroom Stadium attracted interest from a host of clubs, but it was Brentford who snapped him up for a club-record £1m. He's already displayed his blistering speed with his recent goal against Birmingham by outrunning the defence, and Leeds must be wary of that on Saturday.
The Tottenham Hotspur loanee has made a bright start to life at Griffin Park, building on a hugely successful loan spell with Swindon Town last year. Pritchard, 21, has superb quality from set pieces and Leeds must be aware of the service he can provide Brentford's front men. Tipped for a bright future at White Hart Lane, Pritchard's future lies at a higher level than Brentford, and he will be looking to prove that this weekend.
Nothing short of a goal machine in non-league football with Luton Town, 23-year-old Gray signed for Brentford for a fee in the region of £600,000 after smashing 57 goals in just 111 games for the Hatters. Gray is now expected to fill the void left by Clayton Donaldson in the Brentford attack, and he's recently notched two goals in as many games. With pace and predatory instincts, Gray could be the biggest threat to Milanic's Leeds.
