The former sporting director has led the club to the top of the table after five wins from his opening five games in charge, and host eighth-placed Port Vale on Saturday
The former sporting director has guided the Griffin Park club to the top of League One with five wins from his opening five matches and, as a team, Brentford have not lost since October 12, with Uwe Rosler's departure for Wigan Athletic seemingly having little to no effect on his former charges.
And, with Leyton Orient and Wolves faltering over the festive period, the men from west London have moved one point clear at the summit.
Orient, who currently sit second, have just two wins to show for their last seven fixtures, but will be hoping to have turned a corner following a 2-0 victory at struggling Shrewsbury Town in midweek.
They host Carlisle United this weekend, who will be keen to avoid being dragged into the relegation mire with just three points separating them from 21st-placed Crewe Alexandra.
Wolves' season has taken a turn for the worse of late, with the Midlands club having recorded just two wins in their last nine League One matches.
Kenny Jackett's men are without a victory in four, and the visit of fourth-placed Preston North End is sure to focus minds at Molineux as the prospect of dropping further adrift of the top two looms large.
The remaining clubs currently occupying play-off berths - Peterborough United and Rotherham United - face a potentially tricky trip to Swindon Town and a home clash against Crewe respectively.
At the wrong end of the table, bottom-placed Stevenage will be hoping their 3-2 FA Cup third-round victory over Championship side Doncaster Rovers can inspire them to a first league win in seven matches as they head to Oldham Athletic five points adrift of safety.
Meanwhile, second-bottom Notts County host Sheffield United, who dumped Premier League club Aston Villa out of the FA Cup last weekend.
Fellow strugglers Bristol City will look to capitalise on a run of form that has seen Bradford City go on a seven-match winless run when they visit the Coral Windows Stadium, and Tranmere Rovers welcome Walsall to Prenton Park.
Elsewhere, Colchester United host Gillingham, MK Dons face Shrewsbury, and Coventry City welcome Crawley Town to Sixfields on Sunday.
