Spiegel has left Premier League club West Ham to join Portuguese Primeira Liga outfit Boavista.
The Swiss goalkeeper failed to make an impact at the London club and has three different loan spells during his time at West Ham.
Spiegel played on loan at Crawley Town, Barnet and Carlisle United while he was on the books of the Hammers.
The goalkeeper has joined Boavista, and he has sent an emotional message on Twitter to everyone at West Ham.
Spiegel failed to make a single appearance in the Premier League for West Ham, but the goalkeeper will be hoping to feature regularly for Boavista next season.
Boavista finished ninth in the Portuguese Primeira Liga during the 2016-17 campaign.
