Guus Hiddink says Chelsea will “start thinking in a very quick way” if Diego Costa’s injury is revealed to be serious.
Costa was sent for a scan on the shin after Saturday’s draw with Everton, although it is understand the results show no fracture and just bruising.
Speaking before the results, Hiddink admitted that Chelsea could yet delve into the transfer market if there was any bad news.
“Let’s wait on the report. If the negative (happens), then yes, we start thinking in a very quick way,” Hiddink said.
Hiddink on Friday suggested teams making signings in January were “desperate”, but Chelsea have been linked with a host of strikers of late, including Alexandre Pato, Carlos Bacca and Jamie Vardy.
It is too soon to say whether Costa, who was injured when challenging Leighton Baines in the second half, will be able to feature in Sunday’s Premier League clash at Arsenal.
The 27-year-old Brazil-born Spain international reported for treatment at Chelsea’s Surrey training base on Sunday, despite the squad being given two days’ off by Hiddink.
Costa scored Chelsea’s first as the Blues came back from 2-0 down to level at 2-2, with John Terry’s controversial last-gasp goal in stoppage time giving them a point from a 3-3 draw.
The former Atletico Madrid front man had scored just seven times since January 2015 before Jose Mourinho’s departure last month.
But Costa now has five goals in his last five appearances.
Loic Remy could start at Arsenal, with Radamel Falcao out since October with a thigh problem.
