Curacao international Darryl Lachman insists his spell at FC Twente made him a more complete player.
The centre-back opted to join the Owls on Thursday for an undisclosed fee, despite having two years left to run of his contract at the Dutch club.
Lachman, capped four times at international level, struggled to hold down a regular starting spot during the 2014/15 season, making just 15 appearances. His final outing came in their 4-2 defeat against Ajax last February.
Reports in Holland suggest Lachman did not always see eye to eye with Twente coach Alfred Schreuder.
But the 25-year-old feels he has improved as a footballer following that experience.
He said: “I’ve become stronger, my condition is better and I have become a more complete player. I want to still continue to grow.
“Sheffield Wednesday are ambitious and the goal in the short-term is to get promotion to the Premier League. That would be great.”
Lachman, who progressed through Ajax’s youth system and had spells at FC Groningen and Zwolle, is relishing the prospect of meeting his new teammates for the first time next week. The managerless Owls are set to report back for pre-season training on Wednesday.
