Cech retired from Arsenal last year and then joined Chelsea’s management as a team consultant. Then due to the impact of the new crown epidemic, the Blues put the legendary Czech goalkeeper into the Premier League’s 25-man roster this season. But Cech's addition to the squad does not mean that he and Chelsea have signed a professional player contract. He is only used as a preventive measure under the new crown epidemic to prepare for extreme emergencies. As for why it is Cech, Lampard explained: "He is in good physical condition and he is not too old. He can actually continue to play when he retires. He still maintains training and has good physical fitness. Put him into the game. The decision of the roster is easy to come by because he is one of the best goalkeepers in the world. It will be helpful for other goalkeepers to see his state.
