West Brom earned a hard fought three points against Hull City last weekend after Jake Livermore's first half strike was enough to seperate the two teams.
The Baggies have been the standout performers in the Championship this season having only lost once in their opening 16 fixtures which now leaves them on 33 points and two points clear of Preston.
The win against the Tigers extended Albion's current unbeaten run to six following their loss to title challengers Leeds at the beginning of October.
Bilić's side have won four and only drawn two in this run and will be looking to add to their lead following the international break.
However, it won't be easy and here are THREE dilemmas that will be running through the boss' mind this weekend...
No Sawyers or Livermore
The central midfield duo of Jake Livermore and Romaine Sawyers has been key to West Brom's success this season and both have played in every game.
Sawyers has displayed excellent control and creativity in the playmaker role, whilst Livermore has provided the hard work, discipline and breaking up of play for the team.
But, the duo will miss the upcoming fixture against Sheffield Wednesday next weekend due to suspension which will leave Bilić with a tough decision to make when it comes to selecting their replacements.
Having to come from behind to earn points
West Brom have made a habit of coming from behind to secure wins and draws this season and have earned 16 points from losing positions, over half of their current points tally overall.
While it may be impressive, Bilić won't be happy that his team are having to gain points the hard way and the recent results against Stoke and Hull have shown a more structured approach as the Baggies have kept two clean sheets in these fixtures.
Conceding goals at home
Despite being top of the league with a positive goal difference of 12, West Brom have conceded 12 of their 17 goals at the Hawthorns this season.
This is the fifth worse home defence in the league and it has only been the Baggies attacking ability to outscore opponents that has earned them enough points to stay at the top of the league.
The Croatian will be looking for his side to put in more solid performances moving forward as it would be difficult to continue conceding this many without eventually dropping points at home.
