Frank Lampard is under more pressure than Mikel Arteta, according to Tony Cascarino, who says the Chelsea boss has a "real problem" on his hands after investing £220 million ($298m) in the squad during the summer transfer window.
Chelsea sought to build on a promising fourth place Premier League finish last season by bolstering their ranks in a number of key areas.
Big money was spent on Hakim Ziyech, Timo Werner, Kai Havertz, Ben Chiwell and Edouard Mendy ahead of the 2020-21 campaign, but Lampard has only had mixed success in trying to gel a new-look team together.
