The 26-year-old striker was a menace to the Forest backline, as he scored all three goals for Blackburn Rovers in the Championship clash at Ewood Park.
While the game ended in a 3-3 draw, Gestede stole the headlines for his truly sensational performance.
Former Chelsea defender Mancienne featured in the game, and he was impressed with the shift put in by his opponent.
“Rudy is a handful, he is really good in the air, he scored three goals with headers, yeah he is a handful to play against,” the 27-year-old told BBC Radio Nottingham.
“You just have to put somebody on him from goal kicks and corners. Somebody has to stand on his toes, and someone has got to be prepared to jump with him and not give him a clear jump.”
Mancienne’s comments about Gestede raises a key question.
If Forest were aware of the exact nature of the threat posed by Gestede, then why could the defenders not deal with it?
All the three goals that the Benin international scored came from headers, which suggest that the Reds defenders struggled to cope with him aerially.
One suspects that the manager Dougie Freedman would have been preparing his players to deal with Gestede over the week, but the fact that they still could not do what they were supposed to do means that more work needs to be done.
