If you mean the aim of appointing Lampard as an alternative to face important matches like facing Real Madrid, then that is just nonsense. I'm sure Lampard will not be able to do the job well. I think Chelsea management's decision this time again shows their panic in managing the team.
Agreed with you, seems Chelsea's management are panic moment when getting new manager exactly on crucial moment they have return to top fourth standing position in domestic league and have difficult games against Real Madrid on Champion League quarter final. Lampard have bad experienced becoming Chelsea and Everton manager, but don't have ideas with Chelsea's management what their reason pointed Lampard as head coach.
Sure new era under Todd Boehly Chelsea most priority with their manager coming from England, last current manager Graham Potter less experienced and spent much money in transfer window keep failure in Chelsea and waiting how possibility for Lampard bring Chelsea with good achievement than Graham Potter era.
