When it comes to underperforming forwards, Chelsea are pretty much world experts. Since 2011 they have signed Fernando Torres, Alvaro Morata, Romelu Lukaku, Gonzalo Higuain, Alexandre Pato, Radamel Falcao, Timo Werner, Kai Havertz, Christian Pulisic and Hakim Ziyech, none of which have been value for money.
It's a list that makes Blues fans laugh at the poorness of each player, though Havertz still has a chance to overcome his below par Chelsea career - Pulisic and Ziyech fall short of having scored a Champions League winning goal and are not winning over the fanbase.
Although not all of the failed attackers were bemoaned in their time at Stamford Bridge - Torres became a cult hero figure and Werner was praised despite his weaknesses as a Premier League player - the overarching theme of money not well spent is evident.
