Buying so many players in one window was always gonna be a problem (all part of trying to "catch up" with the rest after the transfer ban), even more so during a pandemic season. No pre-season. Constantly playing a game every 3-4 days. Injuries. Players getting COVID-19 (one in Havertz in this case). New players struggling to adapt or needing time to settle in England. Put all those factors together and we ended up with what we have seen. Hopefully we will have a slightly more normal season next time and then we can judge the players better, although the Euros being on this summer is not helpful at all. On top of that, this is like maybe the first time or maybe the first time since 2012/13 or 2013/14 that we went out and bought so many young players, players who are not finished articles yet for the first team, which has led to the struggles/inconsistencies with them. Otherwise, we have tended to buy players in their peak, established players who can come in and make an immediate impact. Not really the case last summer.
