And currently, the biggest question is if Alvaro Morata will start this high profile clash.
Earlier this week, the Blues had received a bid for the Spaniard from Atletic Madrid and various reports are suggesting that the Blues are ready to let the striker move out.
Maurizio Sarri is eager to bring in Gonzalo Higuain to Stamford Bridge this month and that can only happen when Alvaro Morata moves out of the club.
Atletico Madrid manager Diego Simeone has chosen to remain tight-lipped about his club’s interest in Alvaro Morata saying:
“I don’t speak about players that aren’t with us, only those that are.
“I can’t confirm or deny anything because coaches wait to see what the club can do.
“Some players want more minutes, some could be sold by the club, some could arrive. We need to wait until January 31.”
But multiple reports are claiming that the Blues have already made up their mind and want to waste no more time in letting Alvaro Morata move back to Spain.
Will this mean that the Arsenal match will be the final farewell for Alvaro Morata?
Many sources think that the striker might not last even that long.
The deal for Morata could be closed as early as Friday(or even before this article has gone into circulation) and the former Real Madrid man could be on his way back to his homeland before Chelsea head to the Emirates.
This means Maurizio Sarri will hopefully not name Alvaro Morata in the match-day squad and once again it will be Eden Hazard who will play down the middle.
If the Blues manage to pick a win vs Arsenal this weekend then Sarri’s men would go nine points clear from the Gunners.
