The Chelsea star has already said goodbye to his team-mates ahead of his January switch to Shanghai SIPG.
Oscar, 25, will join the Chinese side for a staggering £52m.
Reports suggest the Brazilian international could earn an eye-watering £400,000-a-week.
“This is not a move to further his career”
Jamie Carragher on Chelsea star Oscar
And former Liverpool star-turned-pundit Carragher has slammed Oscar’s decision, claiming it’s embarrassing the playmaker would leave the Premier League in his prime.
“It is a sad day for football when a player about to enter his prime moves for financial reasons and nothing else,” Carragher wrote in his Daily Mail column.
“The money is astronomical, but it’s not as if he is on a pittance at Chelsea. This is not a move to further his career.
“He will talk about the league growing in China, the chance to work with Andre Villas-Boas and the excitement about a new adventure – but we all know those words will be nonsense.
“He has gone for the size of the contract. Nothing else. Players used to look for a pay day in their mid-thirties when their career was coming to an end. We all understood that.
“It is embarrassing that a player would give up his career and the chance to compete for the biggest prizes in the game just for money.”
