22-time grand-slam champion Rafael Nadal has crashed out of the Paris Masters after a second-round loss defeat against American Tommy Paul in just the Spaniard's first match since becoming a father. 

Paul, who is currently ranked number 31 in the world, came from a set down to beat Nadal 3-6 7-6 (7-4) 6-1.

With the exception of a doubles match at Roger Federer's Laver Cup farewell, Nadal had not played since going out in the last 16 of the US Open two months ago following his battle with abdominal injury.

The defeat means the the 36 year old's hopes of ending the year as world number one suffer a huge blow.

The Paris Masters is the final regular ATP Tour event of the season, before the ATP Finals get under way in Turin on 13 November.

European champions Real Madrid suffered a first defeat this season as RB Leipzig rekindled their hopes of booking their place in the Champions League last 16.

Croatia defender Josko Gvardiol scored the opener as he headed the hosts ahead before France forward Christopher Nkunku doubled the advantage.

Vinicius Jr. gave the visitors a lifeline as he reduced the deficit but ex-Chelsea forward Timo Werner made sure of a memorable win for RB Leipzig with the 3rd goal for the Bundesliga outfits.

Real, who had already qualified for the knockout stage prior, scored a late second with a penalty from Rodrygo to end the 5-goal thriller.

With Celtic holding Shakhtar Donetsk in Glasgow in the other game in Group F, second-placed RB Leipzig have nine points, three more than Shakhtar who are in third spot.

Shakhtar host RB Leipzig in Poland on 2 November.
