I could be completely off, but I think El Ghazi is being considered because Richarlison is off this summer. That would leave us Gray/El Ghazi on the left and Gordon/Townsend on the right (gordon/Gray can play either side really - so can El Ghazi). My guess is between the stadium, FFP and our lack of ability to attract top talent a direct replacement for Richy may not be on the cards. Especially when the midfield and central defense need so much work and we still need a striker.
Brennan Johnson fills the same gap (and would be my choice) but i think we are having to be quite creative financially...
