Chelsea manager Jose Mourinho says he will leave the dressing room door open for Arsenal goalkeeper Petr Cech - but only at the end of the game.
Cech, 33, left Chelsea for Arsenal in the summer after 10 brilliant years in Blue, where he won numerous trophies and set records as the club's No 1.
But the emergence of Thibaut Courtois left Cech without much game time last season, and he left - much to the regret of Mourinho - to become Arsenal's first-choice.
Mourinho said that Cech will be welcomed back into his former dressing room after the final whistle has blown.
The XI Chelsea should play against Arsenal
The XI Chelsea should play against Arsenal
1/11 GK: Asmir Begovic
Irony alert. Petr Cech finally quit Chelsea after 10 years because he wanted first-team football - his replacement, Thibaut Courtois, promptly goes and gets injured for around three months. Begovic is as good as a back-up as you'll find in the Premier League and would be a regular starter for at least 10 other teams in the division.
2/11 RB: Cesar Azpilicueta
If Branislav Ivanovic was even playing at a Championship level then he would be in the team, but the Serbian would not get into a League One side at the moment. He's been an absolute liability both defensively and had no impact as an attacker, where he has been so reliable. Cesar Azpilicueta is a stout defender and has the pace and energy to cover the entire right-hand side - that will be key with Chelsea short on wingers for this match.
3/11 CB: Kurt Zouma
Zouma has the pace to deal with Theo Walcott and the strength to deal with Olivier Giroud. As Everton found out last week he is far from the finished article and can be found out with clever movement. But he played better than Gary Cahill in midweek and should retain his place.
4/11 CB: John Terry
Despite his half-time benching against Manchester City, the Chelsea captain has not done much wrong at all this season, but has been badly let down by those playing in front and around him. Father time eventually catches up with everyone, but his organisation and desire mean he should play - besides, Gary Cahill is still not at his level.
5/11 LB: Baba Rahman
Azpilicueta moving over to the right gives Baba Rahman a chance to make the left-back position his own. His added pace and natural left-foot give him an obvious advantage over the Spaniard - who often cuts inside and slows attacks - where he can overlap Eden Hazard to give Chelsea an extra dimension. But, and it's a big but, the young Ghanaian struggled defensively against Maccabi, and was way too often caught high up the pitch and out of position. Chelsea will be ruthlessly punished if he does that against Arsenal. A more disciplined performance is needed.
6/11 CM: Nemanja Matic
His dramatic collapse this season has been just as quick as his meteoric rise to the very top last season, where he overtook Yaya Toure as the best midfielder in the league. Has looked tired, mentally and physically, this season. Got a rest in midweek and knows he must be at his best to combat whatever midfield Arsene Wenger elects to pick. Huge game for Matic, he will be key.
7/11 CM: Cesc Fabregas
It was a surprise to see him play against Maccabi but it was just the tonic the Spaniard needed. His fingerprints were all over the game in a dominant individual performance that brought a goal and an assist and some impressive probing play. Still Chelsea's main creator, Fabregas and Blues fans need to hope his performance translates against a much better class of opponent.
8/11 RW: Pedro
If he's anywhere close to being fit then he has to play - Chelsea just don't have the options in their paper-thin squad. The extremely limited Ramires or the raw Ruben Loftus-Cheek will be the next choices if Pedro misses out, as Willian is out and numerous others out on loan. The Barcelona man started quickly but wasn't at his best against Everton. Still a quality option, however.
9/11 AM: Oscar
Two goals in two starts this season, Oscar's work rate and willingness to defend have made him a Mourinho favourite over the last two years, although that slipped in the second half of last season when the Brazilian badly lost form. The jury is still out on Oscar, who needs to add more flair and creativity to his pretty decent goal record. Has to have a big performance on Saturday.
10/11 LW: Eden Hazard
Not in the team by merit. Last season's Player of the Year looks unfit and (whisper it) a bit uninterested. The Maccabi game should have been a chance for him to find some form, like it was for Fabregas, but Hazard wasn't close to his best, with the early penalty miss knocking his confidence. The weight of burden appears to be hanging heavy on his shoulders, as is the constant double teaming and aggressive treatment he faces from opponents. But it would be far too big a risk to leave him out - plus Chelsea just don't have the options with Willian and maybe Pedro missing. If he doesn't perform then he should expect a spell out of the team.
11/11 ST: Diego Costa
If Mourinho can tell him to stop trying to fight every defender in the land and actually concentrate on his football, he'll have a hell of a striker on his hands. Provided two moments of inspiration against Maccabi, showing quick feet and a turn of pace to win the second penalty, and a telepathic connection - and sublime technique - to volley in a Cesc Fabregas pass. Needs to find his goal scoring form quick for Chelsea to claw their way back into contention. Loic Remy did ok in midweek, but unfortunately was forced to play wide after just 20 minutes because of injury to Willian.
"Arsenal goalkeeper until the game ends. When the game ends, if he wants to come to our dressing room, the door is open for him," said the Chelsea manager.
Mourinho was also coy when asked about Arsene Wenger beating him during the Community Shield, the first time in 14 attempts Wenger had beat his rival.
"I don't think it's important now and I don't think tomorrow people is focused on that. I think people is focused on what happens on the pitch," Mourinho said.
Chelsea are 17th in the standings after their miserable start of four points from five matches, 11 adrift of leaders Manchester City. Mourinho is ignoring everything other than the Gunners.
"If we are looking to the table, I don't think that helps," he added.
"It's a match I want to isolate from every possible context. It's just Chelsea-Arsenal and it's a match that we want to win. If it's a pre-season friendly against Arsenal, we want to win. Community Shield, the same."
