Last week, I swapped Bukayo Saka for Luis Diaz. Arsenal's Saka had a home game against Aston Villa and actually outscored Diaz by virtue of his assist. I'm not unhappy with that switch in the long-term but I would describe that as a luxury transfer. If you've got an injured player sitting in one of the first two spots on your bench - or one who's not starting games regularly - then I would deal with that because I think we're going to need that strength in depth.
