The Chilean has only shone intermittenlty since his huge move to Old Trafford and failed to make an impact as the 'Red Devils' fell to a 1-0 defeat to Chelsea in Saturday's FA Cup final at Wembley.
Since swapping places with Henrikh Mkhitaryan, Sanchez has produced a rather scant return of just three goals in 18 appearances and has failed to stamp his authority on games as many expected.
“I think that in every game I’ve played in I’ve maybe found it hard to adapt to the style of play and I’ve been getting to know my team-mates,” said Sanchez.
Despite United ending the season with no new additions to their trophy cabinet, Sanchez is confident that they will challenge for honours again next term.
“I believe that United really is a very big club on a worldwide scale and even more so in England where it’s the biggest,” the 29-year-old continued. “They always want to win and to be fighting on all fronts and that’s the reason I wanted to come here.
“I also had some great players alongside me at Barcelona, some highly experienced guys who had great quality. I think that United are not too dissimilar as a club to them in their size and stature. However, we still have areas where we can improve, and we can do this day-to-day and a game-to-game basis. I believe we need to improve in all aspects.”
United attracted criticism this season after falling to defeat against all three newly-promoted sides away from home, with Sanchez keen to see an improvement from his side mentally next season.
“We need to be focused and concentrated in the big games and the same in the so-called lesser games too,” he admitted. “That’s what the great sides do and I think United are a great side, so that’s what we need to do. Manchester United is a massive club that always aspires to win big trophies and that is what I’m trying to make happen. I want to try and keep improving so we can see the club winning trophies.”
