The visiting team will be full of confidence after drawing 2-2 with Barcelona's rivals Real Madrid on Sunday and Valverde, who is likely to call upon Lionel Messi and Luis Suarez for the second leg, insists progression to the last eight must not be taken for granted.
It is claimed club president Florentino Perez had planned to woo Messi during a meeting on a private jet with Juarez, sporting director Miguel Pardeza and a Real Madrid lawyer.
Barcelona, nine points clear at the summit of La Liga, completed the finishing touches on Philippe Coutinho's British-record transfer from Liverpool, which could be worth up to £142million, on Sunday evening. Players from the Spanish league dominated the team with five Champions League winning Real Madrid players finding mentions. They'll go down as two of the best ever players.
Real Madrid's Sergio Ramos is also a center-back, along with his right-back teammate Marcelo. Messi's new deal will see him stay at the club until 2021, extending his 18-year spell in Catalonia by another three seasons.
Pedrerol appears to have accepted his mistake, thanking Abidal for the correction and insisting this is how the interview was related on his programme. The only two ratings that Ronaldo beat Messi at was the physicality and the defensive attributes.
UEFA.com shortlisted 50 players on the basis of their performances in the calendar year for the selections of the team of the year.
The retired French defender tweeted: "Correction: When I sent the video to gee up the team Lionel Messi never told me not to send them more stuff like this, nor did he tell me he didn't want to know anything about it".
But it turns out that the figures reported by the media may be inaccurate.
