SHOWS: BARCELONA, SPAIN (MARCH 12, 2019) (REUTERS - ACCESS ALL) 1.
(SOUNDBITE) (Spanish) FC BARCELONA COACH, ERNESTO VALVERDE, SAYING: "The fact that teams like Real Madrid and Paris Saint-Germain have been knocked out is important and we will have to be wary of that in the game, we think that Olympique de Lyon is a great team because of what we've seen them doing in Champions League and of course the fact that these big teams fell last week makes us think that we must be focused.
Regarding Zidane's return he's a great coach, is arriving to a great club and will be our opponent." STORY: Barcelona coach Ernesto Valverde says his side will be extra wary of Olympique Lyonnais in Wednesday's Champions League decider after Real Madrid and Paris St Germain suffered shock eliminations from the competition after second leg turnarounds.
After the last-16 first leg in Lyon finished goalless, Barca have to beat the French side at the Nou Camp if they are to advance to the quarter-finals of a competition which they have underperformed in since last winning it in 2015.
The Catalans are overwhelming favourites to win the game and have an outstanding record at home in the Champions League, remaining unbeaten at the Nou Camp in the competition since losing to Bayern Munich in 2013.
But Valverde said they need to be extra careful after witnessing Real Madrid's 4-1 defeat at home to Ajax Amsterdam after winning the first leg, and Paris St Germain's second leg collapse against Manchester United.
Barca have not lost a Champions League last-16 tie since going out to Liverpool in 2007 but have not gone beyond the quarter-finals since 2015.
Last year's elimination to AS Roma after winning the first leg 4-1 was particularly embarrassing for the club.
Lyon, who are third in Ligue 1 but caused a surprise by beating Manchester City away from home in the Champions League group stage, have been boosted by the return of French forward Nabil Fekir who was suspended from the first leg.
Barca winger Ousmane Dembele picked up a hamstring strain in Saturday's 3-1 win over Rayo Vallecano, although Valverde said there was still a chance he could make the matchday squad for the La Liga leaders.
