According to BBC Sport the flying winger cost West Ham a fee in the region of £7 million and Forest were gutted to let him go.
This week Forest take on Middlesbrough in the Championship and the Boro boss Aitor Karanka has stated this week that Forest are in fact a better team without Antonio, as it freed up wages to bring in several new faces on loan – such as Nelson Oliveira, Ryan Mendes and Jonathan Williams.
“No Michail was a fantastic player for our football club. He did very well in the year he was here and he was a huge threat and I think last year he was a huge threat to Middlesbrough.
“You know the efforts of the new players are great, we are very pleased. We are very pleased with what we have done in the loan market.
“But Michail Antonio, for the situation we were in, I felt it was in the best interest of the football club to sell him. I would have liked to have kept him but the situation we found ourselves in, he had to go.”
Of course Forest were under a Transfer Embargo for the time and selling Antonio gave them room to bring in some more players under their wage cap. They are also expected to be out of FFP regulations by January thanks to the sale of Antonio.
West Ham fans have not yet had the opportunity to see Antonio in full flow. But when they do they are likely to see why Freedman was so keen to keep hold of him.
