Bayern Munich legend Lothar Matthaus has sent a warning to Manchester United, also telling RB Leipzig that they can 'definitely' beat United in their UEFA Champions League encounter on Wednesday.
United will be welcoming Leipzig for their first home Champions League game since their 1-0 Quarter-final loss to FC Barcelona in 2019.
Last week, United put up a fantastic counter-attacking display against Paris Saint-Germain, winning 2-1 at the Parc des Princes thanks to a late winner from Marcus Rashford.
The next game will not be easy either, coming up against a Leipzig side that is currently top of the Bundesliga after picking up 13 points from a possible 15 in their first five league matches of the season.
Leipzig also got off to a winning start in Europe, winning 2-0 against Istanbul Basaksehir.
Last season, Julian Nagelsmann's side raeched the semi-finals of the competition, and on their road to the semis, they beat the likes of Tottenham Hotspur and Atletico Madrid.
German legend Matthaus is backing RB Leipzig to come out on top, pointing towards United's league position (15th) as one of the main reasons as to why the German side should not fear a trip to Old Trafford.
Speaking with Sky Sport, the German said "For Julian Nagelsmann and RB Leipzig, the next highlight is the game at Manchester United."
"The Bundesliga leaders are seamlessly building on the great last season. The team has become even more mature and grown up."
He added that "After the departure of Schick and Werner, Poulsen and Forsberg are experiencing something like a second wind."
Praising Leipzig even further, he added that "The team now finish off games without taking unnecessary risks. The 2-0 win against Basaksehir or the 2-1 win against Hertha Berlin show that Leipzig are becoming more stable and that they are very intelligent at work."
"Anyone who made it into the Champions League semi-finals last season doesn’t have to hide from Manchester United either. No matter how big the name is, the United team shouldn’t intimidate RB Leipzig."
He also hinted at the Premier League table, saying that they have had a number of "meagre" results, concluding that "Leipzig can definitely win".
