Lovell is by far the better player, he hasn't really delivered and is generally injured and when he has had a chance he hasn't looked overly keen to grasp it, in fact, at times, he has looked thoroughly uninterested and that is the most annoying thing about him.
We all asked for him to get a chance, when he got it, he genuinely looked like he couldn't give a fuck.
A player that really should have cemented himself in the team and I agree with BTR, we may well not replace him properly but we at least have an opportunity to replace him with someone who gives a flying fuck.
Mackie is not as good as Lovell, plenty of effort but to score fewer goals than Lovell with the number of starts he's had is pretty mediocre. Both are infuriating for missing very easily convertable chances, but Lovell is a far better player with a far inferior work rate.
