Isn’t it the case that the clubs who have no HG problems, have, well, no HG problems? Meaning they can operate with a greater flexibility in the market? We have a problem with it.
We also need to maintain a large squad in case of injury or Covid, as well as the number of matches we are playing. We would also need to persuade one of the players you mentioned to leave the club, where they seem happy at. And persuade some other team that they are good enough to buy but not good enough for us.
Then we need to find a HG player that we can afford, that would improve our first team. Very very few spring to mind. No point in selling a decent squad player to buy another. Unless we are also planning to buy a top quality first team foreign player? If that’s the case, where’s the money coming from?
I don’t think transfers and squad balancing / building is as easy a fix as many believe. Especially not in January.
Here are some easy solutions we could have done to have HG not be an issue. Not all of them are necessary ideal and some may not have been possible but the point is that we have HG issues because the club has chose to not care about it and handcuff themselves:
Buy Bowen instead of Bergwijn
Buy White instead of Rodon
Buy Eze and move any one of Lamela, Moura, Sissoko
Buy Watkins instead of Vinicius
Buy Demari Gray and move one of Lamela, Moura, Sissoko
Buy Jude Bellingham
These are all possible moves based on players that have recently moved. I am sure there are more that I missed and some that we could have made that we as fans don't know about. The point is that there are always options to make moves on HG players. The complaint that it is hard or can't be done is false. We have chose to put ourselves in this position as a club, there are always options to bring in HG players, especially when the team has so many foreign players- Lamela, Moura, Sissoko, Gedson, Sanchez, Doherty/Aurier that it could easily move and not miss a beat.
