Not the whole reason but big part of the reason. Two key players are Lisandro and Shaw not only in defense but also in build up, transition and attack. So to lose both for long periods had impact. Another big reason was that Bruno and Rashford's form fell of the cliff, Casemiro legs have gone like being cut by a lawnmower and also we didn't sign another quality forward. Add to that Sancho issues, Greenwood issues, rawness of Garnacho and Hojlund, absolute and total disaster of Antony, few Onana blunders, ETH inexperience at this level and you have quite a mix of circumstances attributing to our shit football. There were a few bright spots with revelation of Mainoo for example, a few wins over Poll and City and cup success. Let's see if ETH can build on that but with fully firing Lisandro, Shaw, a new elite midfielder engine, Rashford finding any semblance of form and another experienced forward to take on the striker workload, and maybe another half decent winger we could have a foundation of a solid team.
