Difficult to know isn't it?!
I think Haaland will start whilst they're still fighting for the title.
Similarly, Chelsea need top 4 (or top 5 if they're lucky) so they can't afford to drop points either.
Given the International break and then FA Cup, I expect both players to play this weekend and then in the Champions League - perhaps an early sub if they're strolling to victory.
