Viktor Fischer has ended his dismal time at Middlesbrough after just one year.
It looked as though Aitor Karanka had pulled off one of the potential bargains of last summer when he landed Fischer, who arrived from Ajax in a deal worth around £4million.
The Denmark international was regarded as one of the hottest prospects at the Dutch club, for whom he has scored a total of 33 goals in 111 appearances in all competitions.
However, the 23-year-old, like many of his new team-mates at the Riverside Stadium, struggled to find anything like his best form as Boro were relegated from the Premier League.
Fischer played just 16 times for Boro as he struggled with a knee injury, and he has now ended his nightmare spell by signing for German club Mainz on a four-year deal.
“Mainz is the right club for me to enjoy my football again,” he told their official club website. “I want to be a part of this team and this club quickly. I want to bring my qualities as an offensive player.”
It is unclear how much the Bundesliga side have paid for Fischer, who has 15 international caps, but it is likely to be for a fee similar to that which Ajax received last year.
