Chelsea have spent more than £500m on bringing in 17 new players during the last two transfer windows but the lack of a clinical striker was made painfully clear as the Blues failed to score in a 0-0 draw with Fulham on Friday.
Pierre-Emerick Aubameyang, Chelsea's only fit number nine, has been left out of the club's Champions League squad and did not feature at all against the Cottagers as a number of big-money arrivals made their debuts.
Argentina's World Cup-winning midfielder Enzo Fernandez, who signed for a British record sum of £107m on deadline day, impressed but that lack of quality in the final third told as Chelsea's top-four hopes were dealt another blow.
