Chelsea boss Maurizio Sarri has called for attacking reinforcements in January and indicated he wants the club to bring in a striker.
The Blues drew a blank on Wednesday as they were held to a 0-0 draw at home to a Southampton side that had not kept a clean sheet in their previous 10 Premier League games.
Per the Press Association's Matt McGeehan (h/t MailOnline), Sarri said: "On the bench I tried to do my job. I think we played a very good match for 80 metres of the pitch, then we were in trouble in the last 20 metres.
