Wenger's latest interest comes days after Bayern Munich chiefs sacked Niko Kovac following their shocking 5-1 Bundesliga defeat at Eintracht Frankfurt.
"It's OK for people to demand (more)", said Valverde after the game, according to Marca.
"The other day we lost against Levante and it does not escape us that the last two have not been our best matches", Valverde told Movistar. Today, the truth is that we have not been right (when it has come to converting the) clear chances that we have had. In football, everything happens very fast.
"We couldn't convert the dominance we had into opportunities".
Barcelona remain top of Group F, although Borussia Dortmund reduced their advantage to a single point later on Tuesday evening by coming from two goals down to beat Inter Milan 3-2 in Germany.
"We know there is a lot of pressure on the team and we have to respond".
"Jordi has a hamstring problem and we'll see what the doctors say", said Valverde.
Slavia Prague goalkeeper Ondrej Kolar put in one of the performances of his career at Camp Nou.
"I would ask for a little patience", added Pique.
Barcelona now sit at the top of Group F in the Champions League with eight points, one point ahead of Borussia Dortmund and four ahead of Inter Milan.
"We don't have any time to sit around and get anxious, we have to keep working and play every three days". And for one of the competition's biggest favorites, this is a key game, not only in terms of qualification for the Round of 16 but also to get some confidence back after a very bad result over the weekend.
That said, we can not say whether the keeper lied or not because there are no images of what occurred in the tunnel.
Lionel Messi has failed to score in back-to-back Champions League matches for Barcelona at the Nou Camp for the first time since March/April 2015 (v Manchester City and Paris St-Germain).
