After a routine win over CSKA Moscow in the Champions League, the RTÉ panel accentuated the positive things that Manchester United have going for them at the moment, but yet they feel there is an element missing that would make them a really great side.

A double from Romelu Lukaku helped United to a 4-1 victory in the Russian capital.

Reflecting on the performance, Eamon Dunphy said: "The attitude from United was very, very good. It's a good, strong result. If you want a comparison, Liverpool, who played Spartak on Tuesday night, a team below CSKA in the league, they couldn't get the job done.  

"I think Jose Mourinho will be annoyed they gave a goal away. Concentration levels dropped after he made some changes."

Liam Brady, while also complementing United's performance, did add that something is missing to make them even better.

"There is an X Factor missing at United - a really world class player that can make a difference," he revealed.

"I'm talking about players like Ronaldo, Messi and Bale. I'd even throw Coutinho in - a player that can change a game on his own. I don’t  think Manchester United have that, even though they have power and they have the strength."
