It’s been nice seeing the boys come back to pre-season in good shape,” he told talkSPORT on Thursday.”But then again, no points have been handed out, and it doesn’t really matter when Chelsea come to Old Trafford on 11th August.”Solskjaer added: “We need to improve and we need to be better. The more we improve and the more we get better, the bigger the chance we can challenge for trophies at the end of the season.”These boys have shown their capabilities. If we just stay level-headed, I can see us improving a lot.Solskjaer helped the Premier League giants briefly turn their form around last term after replacing Jose Mourinho at the helm in December.The Red Devils won 15 of his first 17 matches in charge across all competitions, restoring the feel-good factor around Old Trafford for a brief period.However, United won just two of their final nine league games of the season, finishing sixth in the table and failing to qualify for the Champions League.Solskjaer, confirmed as permanent manager on a three-year deal in March, feels the difficult campaign eventually took its toll on his players.”Football is an emotional game. It’s always difficult when a new manager has to come in and the previous one loses his job, but the players handled it well over the summer and they’ve come back really fit and sharp,” he said.”I know how fine the margins are in football and how easily things can go from good to bad. It’s a mental game, it’s all in the head.”We didn’t handle the ups and the downs well enough, we know that. That would be down to mental tiredness because it was a draining season for everyone, but we’ll be better this year.” Check out Goal’s Premier League 2019-20 fantasy football podcast for game tips, debate and rivalries.
