Chelsea are looking to hand more players with transfer deal as they are reportedly looking to hijack Man Utd’s signing of Ecuador star Moises Caicedo.
Chelsea’s England full-backs are Frank Lampard’s main injury doubts, with Kai Havertz already ruled out.
Boss Lampard even rates James and Chilwell uncertain to make Tuesday’s Premier League trip to Brighton.
But Lamps’ main focus is on ensuring his fifth-placed Blues show no complacency against the lowly Gunners.
He said: “When you play a derby, form does go out the window.
“Sometimes the idea of playing a derby is the spur the team needs to try and get a result.
“We have to expect the best Arsenal which is a really good footballing team with really good players, well-coached with rotations in their team and threats in attacking areas.”
Meanwhile, Chelsea left-back Marcos Alonso has been linked to both Atletico Madrid and Inter Milan.
And the Blues are reportedly duelling Manchester United for Independiente del Valle’s Ecuadorian winger Moises Caicedo, 19, rated at £4.5million.
