While Everton were able to leave Stamford Bridge with a good point on Sunday following their 0-0 draw with Chelsea, not everything was positive.

Icelandic playmaker Gylfi Sigurdsson limped off on 76 minutes in clear discomfort following a poor challenge from Jorginho in the first half, which should have seen the Italian sent off.

The 29-year-old is now set to miss Iceland's upcoming UEFA Nations League match versus Belgium and, should he not recover in time for Everton's next Premier League game after the international break, it would come as a massive blow to manager Marco Silva.

After a disappointing debut season at Goodison Park, Sigurdsson has been brilliant so far this campaign under his new Portuguese boss, playing in his more preferred No.10 position.

With that in mind, now is the time for Bernard and Theo Walcott to step up in any potential absence of the Iceland international.

While Bernard has shown glimpses of his quality since arriving at the club back in the summer, the Brazilian has fallen short when good opportunities to score have fallen to him.

Likewise, Walcott has also failed to capitalise on a few very promising attacking moves in recent weeks with either his touch or tendency to run in behind too early costing him.

The two, though, are still individuals who possess a lot of quality, quality which Everton could desperately do with if Sigurdsson is not fit enough to play against Cardiff City.
