Chelsea open their Premier League title defence against Burnley at Stamford Bridge on Saturday after a summer of speculation.
The arrivals of defender Victor Lindelof, midfielder Nemanja Matic and striker Romelu Lukaku have also improved the squad.
"It's going to be a challenge for everybody but we'll take it in our stride, compete and we'll surprise a few people", March told The Times newspaper.
"I'm doing my best every day".
"They could have scored more goals than they did, we could have scored more goals than we did..."
"We lost only one match at home and in the cups we never lost, but too many draws".
The first club to be promoted to the English Premier League was Brighton & Hove Albion after winning against Wigan Athletic on April 17, 2017, at home.
While the League Cup is little regarded, the Europa League provided a ticket into the Champions League - and probably the signature of Lukaku.
"They are always strong at Old Trafford and will believe they are getting back towards being the side that was feared during the Alex Ferguson era".
"They need better in there, they need more dynamic better quality player in that central midfield area".
"I think we played everything so we don't lose this game", the Serbian said after a performance that thoroughly impressed Mourinho. I understand by doing 75 percent of what I asked, the club did very well. Middlesborough suffered a similar fate after a 3-0 away defeat to the defending champions; Chelsea on May 08, 2017, while Hull City completed the relegation teams following a 4-0 away defeat to Crystal Palace on May 14, 2017.
Crespo added: "I think the top four will be Manchester United, Manchester City, Chelsea and Arsenal".
Herrera says United simply came up short against the "best team in the world" - a philosophical stance that echoed his manager's post-match thoughts.
The tactician continued, "He thinks he can do more and wants more at the highest level, so we're having conversations and we're discussing the possibility of him to stay with us for the second part of the season.". "Old Trafford is waiting for us and I think Old Trafford has a reason to be behind us", he said.
Former Manchester City pair Joe Hart and Pablo Zabaleta and star signing Marko Arnautovic, a £20 million recruit from Stoke City, could all make their competitive debuts on Sunday.
