Answer
John Guidetti was playing in the Dutch Eredivisie when he joined Celta Vigo in the summer of 2015. The Swedish striker had been in impressive form for Feyenoord, scoring 20 goals in 33 league appearances during the 2014-15 season. This led to interest from several clubs across Europe, but he ultimately chose to join Celta Vigo, who were playing in La Liga at the time.
