In one sentence – Gilberto, prosaic, did his job very well indeed.
There’s a nice tribute to him on the Arsenal website, do have a look (click here).
The Brazilian never courted controversy and never spoke out of turn. He arrived quietly, he left quietly and, in between, he was quietly efficient. While emptier vessels made more noise, Gilberto just got the job done.
He will be missed. Thanks, and cheers!
