Owen Hargreaves says Dynamo Kiev were "afraid" of Manchester United when they met in Ukraine two weeks ago.
Providing Ferguson's side can confirm their superiority over Kiev at Old Trafford on Wednesday, they will book a place in the knockout phase with two games to spare.
And Hargreaves, who is set to make his long-awaited Champions League debut for United after finally overcoming the knee problem which blighted the early weeks of his Red Devils career following an £18million summer move from Bayern Munich, can see no reason why Ferguson should not receive a perfect 21st anniversary present as manager.
"Dynamo seemed a bit afraid of us in Kiev," said the England midfielder.
"It is very rare in the Champions League that you see someone pulled apart so easily and concede four goals at home.
"Normally, those type of games are very difficult but Dynamo were really quite poor, surprisingly so for that level of competition."
