Flamengo fullback Filipe Luis believes Antoine Griezmann wasn't giving his all for Atletico Madrid last season.
Griezmann left for Barcelona last summer.
And former Atleti defender Luis told Marca: "I understood it.
"He'd been there for a few years and wanted something knew. He gave a lot to Atleti and returned everything the club invested in him.
"Being at the same place for a long time can lead to comfort that no longer motivates, so we all understood him and remember him fondly."
