Sanchez took a full part in Arsenal's training session yesterday before the game.
Faced with the daunting task of trying to overturn a 5-1 deficit against Bayern Munich in the Champions League last 16 second leg, Wenger knows the critics will be sharpening their knives again on Tuesday and he can't expect any sympathy after this weird selection gamble.
Much of their threat came through Alexis, who drew the attention of Liverpool defenders all half.
The 28-year-old trained with the squad as normal on the eve of the Bayern clash and shook hands with Wenger as he made his way onto the club's London Colney training pitch.
"I'm not aware [of a falling out]".
Emre Can and Ragnar Klavan started for the hosts but it was the visiting team's change that made social media go into a frenzy as Arsenal manager Arsene Wenger perplexingly chose to bench talismanic winger Alexis Sanchez in favour of Olivier Giroud.
"I understand you have to feed the newspaper and we respect that", a calm Wenger said. "He is a committed player, sometimes with excessive behaviour, but you have seen that many times in history in every squad".
The Arsenal manager is also wary of playing his team's first game in 12 days on the back of Liverpool's poor performance at Leicester after a similar break between games. Our game is built on collective expression. "I have no regrets, except that we lost the game".
The Reds have been excellent against teams in the top six of the Premier League this season, beating Tottenham Hotspur, Manchester City, Chelsea and drawing with Manchester United twice. "We wanted to play two players who are strong in the air (Olivier Giroud and Danny Welbeck) because we chose to go more direct".
Andy Murray survives 38-point tiebreak to reach Dubai semifinals
And Murray quickly wrapped things up, clinching the match with a powerful serve which Verdasco could find no response to. Murray lost his first two service games of the match but overcame that poor start to win in Dubai for the first time .
"The decision will depend completely on Arsenal Football Club". Wenger also went on to wax philosophical about what makes a player happy, saying that "the definition of a happy person is very hard. I hope he is happy tomorrow". Let's not fool ourselves, we have a one or two-percent chance. "It was a odd game to leave him out of, it baffled me".
Sanchez yesterday issued what sounded at first like a ringing endorsement of his commitment to Arsenal when he wrote on Instagram: "The true warrior fights not because he hates the ones in front of him, but because he loves those behind him".
"We did try to go direct, by which I mean I wanted the goalkeeper to kick it straight to the strikers", he said.
"A decision like that is not easy to make", Wenger said, "but you have to stand up for it".
"Your questions are not adjusted to the press conference when preparing for a game".
"The performance tonight should not be a surprise because the boys have played already a few times like this".
"The board chooses the manager". At this stage in the season, you are who you are.
I'm not suggesting that he should have to but Liverpool desperately need players who can lead and inspire. The media will jump on the fact that United are dropping their most expensive player.
