Arsenal host Everton at the Emirates knowing a fourth consecutive win will see them move to the top of the table, for at least one night.
Arsene Wenger’s side have won their last three league matches by three goals and defeated Bayern Munich 2-0 on Tuesday, while the Blues come into this on the back of a heavy home defeat to Manchester United.
The reason why Arsenal have suddenly clicked has been largely down to Alexis Sanchez.
The Chilean has scored six goals in his last three league games but Wenger expressed that he’s worried his star is tired after four games in 12 days.
Despite that, Sanchez is expected to start once again but Aaron Ramsey is on the sidelines with a hamstring injury.
Someone who could come into the team to replace the Welshman is striker Olivier Giroud.
The Frenchman has scored four in four against the Toffees and netted the opener against Bayern.
However, that would mean Theo Walcott pushing to the right hand side, so Alex Oxlade Chamberlain is the most likely to come in for Ramsey.
David Ospina and Mikel Arteta are also sidelined along with long-term absentees Jack Wilshere, Tomas Rosicky and Danny Welbeck.
Petr Cech will be looking for his 168th Premier League clean sheet. He is just two off the record held by David James.
Everton’s defeat at home to Manchester United last week was unexpected as they have otherwise looked impressive this year.
Roberto Martinez will hope confidence has not been hit as a perfect performance will be needed to improve a record which has seen the Toffees beat Arsenal just once in 16 attempts.
Romelu Lukaku continues to be a frustrating player, looking like a world beater one week and off colour the next.
It’s easy to forget his is just 22 though and he needs just three goals to reach 50 in the Premier League.
Martinez was handed a boost midweek as Tom Cleverly, Bryan Oviedo and Steven Pienaar all played a part in an under-21 game on Tuesday.
All three could make the bench on Saturday but Leighton Baines and Muhamed Besic are still a week or two away from full fitness.
