Championship football was a shock to the system for Ayoze Perez.
But the Newcastle forward believes the learning experience away from the big time has made him much better equipped for his return.
Perez was one of the slower starters in the Magpies squad last season, only really coming into his own towards the back end of the campaign as United overturned a seven point deficit to Brighton, to lift the second tier trophy on the final day.
Despite an 'in and out' start to the season, he ended it with nine goals in the league, 12 in total - his most successful year since his switch from Tenerife.
The Spaniard admits that he found life outside the Premier League "hard", as he maybe took longer than others to acclimatise to the high-paced, rough and tough of the Championship.
But he is hopeful that some of the difficult lessons learned last season, will aid him with United now back where they belong.
