The 40-year-old says he has a "good relationship" with his manager and believes the Red Devils are not underdogs heading into their Champions League tie with Bayern Munich.
At Monday's press conference Giggs was prevented from responding to a journalist who asked whether his aim is to eventually become United's manager, but the player dismissed reports that suggest there is a rift between himself and the Scot.

“The last time I played was probably the first time in six or seven weeks but we've got a lot of players to choose from, and as you see in the performance against Olympiakos I'm always ready to come in and play. And that's what you've got to do: not sulk because you're not playing. You've got to come in and be ready to play for the team.
“The players tomorrow if they've not been playing have got to come in and perform.”
Following Giggs’ response, Moyes interjected jokily: "I'm doing his yoga classes now, maybe that will help me.”
United hosts Bayern Munich in their Champions League quarterfinal first leg on Tuesday.
The two sides head into the fixture with contrasting campaigns. While Bayern has already won the Bundesliga, United finds itself far behind the title pace and will record its lowest points total in the Premier League this season.
But Giggs has rejected the idea that the Red Devils are approaching the contest as underdogs.
“Obviously Bayern are a fantastic team. They are the holders. Pep Guardiola has took over, added a few new players and obviously they are a very strong team,” he said. “And like you say, probably favorites in most people’s eyes. But we’re Manchester United, it’s at Old Trafford and we have seen so many great nights in Europe especially.
“As players, we don’t see ourselves as underdogs. We see ourselves as Manchester United playing at home in the Champions League and we can’t wait. These are the games you want to be involved in as a player. We’ll go out and try and win the game, it’s going to be tough but it usually is in the quarterfinals of the Champions League, but we’re confident, we’re looking forward to it.”
