After facing and beating them in the champions league match on Wednesday, Mourinho believes Kiev can win the Europa League.
Chelsea welcomed Kiev to the Stamford Bridge and triumphed by 2-1 to jump to second on the log of the group G.
And should the Ukrainian club fail to make it out of the group stages, Mourinho believes they can challenge and possibly win the Europa.
“I have to say Dynamo are a very good team,” Mourinho said.
“I already told Rebrov and Sheva [Andrei Shevchenko] because they were here together.
“This Dynamo is much better than the one I played against with Inter in 2010. In the last 10 years you look at Russian and Ukraine and you don’t think the teams are very good but it’s changing. To beat them is difficult.
“I knew it would be difficult to score and they are good on the counter attack. They have five giants from set-pieces and it’s difficult to control them. I knew the risks but in the first half we were very good and we deserved a different result.
“In the last part of the game the normal tendency is that if the game went on for another five or 10 minutes we would score more goals because the game was open.”
Mourinho added: “I hope they go to the Europa League, which would mean we go to the Champions League last 16, because their team in the Europa League will be a real contender.”
