Lacazette has been out of action since undergoing knee surgery after the 1-0 loss to Tottenham Hotspur at Wembley back at the start of February.
However, the French striker is now back in action at London Colney and looking to get back fit as quickly as possible to help Arsenal in the closing months of the season.
Lacazette took part in a full training session with his Arsenal team-mates on Monday as the Gunners began their preparations for their home clash against Stoke City at The Emirates in the Premier League on Sunday.
And Spanish full-back Bellerin was clearly pleased to welcome his team-mate back to action for the north London side this week.
Bellerin posted the picture above on his personal Instagram account and wrote the caption: “My face when I saw @lacazettealex back in training 😃.”
Arsenal are currently in sixth place in the Premier League table as they look to try and break back into the top four before the season is out.
The north London side will take on CSKA Moscow in the first leg of their Europa League quarter-final clash next Thursday.
