In my mind, we didn't replace Johnson with Gallagher. We picked up a long term injury to Bents and brought in more midfield depth. We took a gamble on releasing Johnson to bring in a player like Semenyo.
It's all become blurred because Johnson left and Kudus got injured within days of each other. Then Odobert got injured on 10 Feb, so the consequence is that we've seen Conor play out of position.
It's an absolute stretch to tag Gallagher as Johnsons replacement.
The list of players in our squad who can play right forwards is endless - Kudus, Kulu, Richi, Muani, Tel, Odobert etc. Then you have the narrower ones like Bergval, Sarr, Gallagher and a wild card like Spence.
We'd never really be short in that position but we definitely need more quality in the left and right forward positions.
It's a stretch for us but I'm not sure what Lange and co are capable of tbh.
