Paris Saint-Germain coach Thomas Tuchel has rejected the idea that Neymar and Edinson Cavani's absences will change the Ligue 1 club's approach for the first leg of their Champions League round-of-16 clash with Manchester United at Old Trafford on Tuesday.

Neymar misses out because of a second fractured fifth metatarsal in his right foot in as many years, while Cavani injured his right hip just last weekend, but Tuchel was adamant that his PSG side will still look to attack.

"Of course, we will miss the likes of Neymar and Edinson in attack," said Tuchel at his prematch press conference. "Neymar is our key player, one of the best in Europe, but we still have our identity.

"We will not change our approach just because of these absences. We are used to playing attacking football -- it is in our DNA. Changing now would be difficult.

"There will be moments when we need to defend deep, as I expect United to attack us, but we must be at our best everywhere. That said, we are here to score -- that is clear."

Tuchel also dismissed the notion that Kylian Mbappe must step up without Neymar and Cavani and tried to temper the expectations around the France international.
