6 Truths: Luk-aku at what the Champions League's been missing, all fear MNC

Romelu Lukaku is demonstrating why he was so unhappy being separated from Champions League football for so long. The Belgian became the first Manchester United player to score in each of his first two Champions League games as he netted a brace against a hapless CSKA Moscow and continued his sensational run of goals in the process.

Lukaku has now scored a staggering 10 goals in nine games for United in all competitions so far this season and it seems as though he’s just getting started. The goals are coming so easily for him that there are no signs of his form abating. His movement, positioning and touch in front of goal are so impressive and he’s showing what the Champions League has been missing.

It seems fashionable for opposing fans to moan about the wealth and approach of Paris Saint-Germain to the extent that the club is unfairly represented. Amid all the record signings and lavish spending it is easy to forget just how spirited and passionate the club’s fans are.

Before kick-off at the Parc des Princes for PSG’s Group B clash with Bayern Munich, the atmosphere was incredible and the home fans generated an unbelievable amount of noise. Nothing much changed throughout the match and it’s time the club’s raucous fans are recognised, regardless of how much money the owners have spent.

The way Romelu Lukaku has been playing it’s hard to imagine how he could really improve in a United shirt, but Jose Mourinho found a way to take his striker’s form to another level against CSKA Moscow – by putting Anthony Martial alongside him. The addition of the Frenchman next to Lukaku created something very special as the pair instantly developed a magical partnership.

United looked unstoppable at times with Lukaku and Martial thriving alongside each other and Mourinho must ensure that the duo are unleashed in the Premier League as often as possible given how dynamic and in sync they appeared to be. The United boss may have stumbled upon something very special indeed.

Bayern Munich simply had no answer for PSG’s fearsome trio of Kylian Mbappe, Neymar and Edinson Cavani. PSG’s deadly strike-force set aside differences to put on a scintillating display in Paris, and while Cavani and Neymar were both on the scoresheet, Mbappe turned Bayern’s defence, and namely David Alaba, inside out.

The Premier League champions faced Europe’s immoveable object, Atletico Madrid at home, and came back with all three points. In doing so, Chelsea become the first away team to win at the Wanda Metropolitano, and it was no more than their performance deserved.

Eden Hazard shone throughout, and with his ankle problems seemingly behind him, his link-up play with Alvaro Morata could prove to be their key to success this season. Add Michy Batshuayi’s knack for important goals and you have a recipe for further glory.

Barcelona, featuring Lionel Messi and Luis Suarez, were merely a sideshow in Europe tonight as events in Paris and Madrid took centre-stage.

But what was missed by many was a gritty victory over Sporting from a usually-flashy Barcelona side. And there was a bang-average winner to boot, which in fact came off the chest of an opposition player… Messi’s wait for his 100th European goal goes on, but it’s unlikely he’ll have to wait much longer.
