Sanogo dug up an old tweet from Fabregas in 2011 pledging his love for Arsenal, and he retweeted it to his following north of 105,000 followers.
It was shortly after deleted but not before being captured and spread around.

Fabregas left Arsenal in 2011 to rejoin boyhood club Barcelona and moved back to London, albeit in blue, to Chelsea this summer.
Even though Arsenal had a well-documented buy-back clause to first bring Fabregas back that they neglected to use, there's still a bit of hostility aimed his direction in north London for leaving in the first place.
