I'm not sure that we couldn't have improved the squad relatively easily this season. We went into the season knowing that Mousa and Victor were ravaged by injuries. We could have taken Gomes on loan or Dendoncker or a number of other options. No, they're not as good as the 2 that we had were in 2016/17 but they would have been significantly better than they were this season.
Given Eric Lamela's injury problems, maddeningly, we passed on Tielemans, also a loan option.
Improving on Kane, Eriksen, Super Jan, etc. probably is impossible at our stage of development but we're light by 2 or 3 players and that needn't have been the case. Most annoyingly, we could have done it with minimal outlay and within our wage structure.
