Simms is not going to be used unless we really are down to the last legs - that's the view of the club.
Tosun is being used as third-choice but he isn't fit.
Regardless, we needed a 'forward' - not particularly a CF. We needed a player to play in any of the three roles up front and give us a potent threat, even if not the same threat as Richarlison/James.
It's about mitigating risk in a season which has more risk due to fixture congestion (including daft international breaks of three games) and COVID.
We didn't mitigate that risk, and it could be seen a mile off.
