However, Arsenal manager Unai Emery has suggested that Welbeck will stay at the Emirates Stadium, which could open the door for Everton and Newcastle to make moves for him in the January transfer window.
Emery urged fans to go into the City game and the season with optimism and said he wanted his players to take one step at a time.
Leroy Sane may also feel he has a point to prove after not making it into Germany's World Cup squad, and looks a good value longer bet at 17/10 (2.70) considering he has scored in three of his previous four league meetings with this opposition. It's for that, my message for Sunday and for the season is optimism. But for me, I want to enjoy the way [we do it]. "With the same players and also our new players with us, and with a new culture and new staff".
"Today, Nacho Monreal began to train with the team", Emery said.
"But we are starting a new way, a new process with the same players and the new players, the new coaches".
Jose Mourinho 'desperate' for strong Manchester United start
Leicester have failed to win in 7 previous Premier League matches against Manchester United with only one victory in last 18. Since then, he's fallen out of favor at times at United under Mourinho and was unable to sustain consistent playing time.
"We are working on the possibility to work with Ainsley, who has experience in this position. I am going to decide tomorrow [Saturday] on the first 11, but Ainsley is the player who started the last match against Lazio".
Bernd Leno joined from Bayer Leverkusen to offer an alternative to ageing goalkeeper Petr Cech, while Lucas Torreira and Matteo Guendouzi have been bought to add energy and steel in midfield.
Danny Welbeck has been linked with a move to Valencia by the British media, with major European leagues able to recruit players until 31 August. "These five players are in this possibility to be the captain". But in these two moments in the match we need to work. "His career as a coach is also bigger than mine".
Arsenal had been stuck in a downward spiral for years and with Wenger unable to reverse the decline, owner Stan Kroenke finally dispensed with the most successful manager in his club's history despite the Frenchman's desire to stay.
