Chelsea fear they will be left chronically short in attack when they face Arsenal next Sunday, so much so that they are considering the signing of Alexandre Pato, reports the Telegraph.
They have already had to endure most of the season without Radamel Falcao, who through either poor form or injury, has been unavailable for selection. Now, Diego Costa has added to their worries after he went down with a leg injury in Saturday's game against Everton.
The Spain international was forced off in the 80th minute during the 3-3 draw and was sent to hospital to undergo scans on his tibia. It had originally been suspected that he may have suffered a fracture, but it has now been confirmed to be just bruising.

That has ruled out a lengthy lay-off, but Chelsea are yet to place a timeframe on Costa's return, leaving him as a major doubt for when they travel to the Emirates. Only Loic Remy, who has made his intentions to leave Stamford Bridge this month clear, is currently available to Guus Hiddink.
But there could be a new name on the Chelsea team sheet by the time next Sunday rolls around. The Blues have already spoken to Brazilian club Corinthians over Pato and there is a suggestion from the same report that a transfer move could be accelerated in the coming days.
Pato recently confirmed his intent to move to England and, with several Brazilian nationals already in the squad, Chelsea would represent something of an ideal move for the former AC Milan star.
He said last month: “One day I knew I would like to come to England because I think the Premier League is the number one in the world. It is very competitive. I like the emotion in the English league."
And Pato's arrival at Chelsea could spell the end for Remy. The Frenchman is keen to seal first-team football ahead of Euro 2016 and isn't going to get it at his current club. He has a lucrative offer from China but has several suitors in the Premier League as well.
However, Chelsea may have to wait for Costa to return to full fitness before sanctioning Remy's exit.
