Goalies are weird animals. Going from being the starting goalie for years to becoming Jason Steeles sidekick... Essentially getting the blame for a few poor results. National team selections coming up in a few weeks. Not at all...

Personally wouldn't be shocked if this we've seen the last of Sanchez in a Brighton shirt.
