Cut from the squad
Matthews suffered the same fate as many players this week who were all given the heartbreaking news that they weren't a part of their team's final plans, with Paul Dummett also missing out on a place in the team.
Chris Coleman opted for only seven defenders on the trip to the Euros and therefore both men were not needed alongside midfielder Emyr Huws who also missed out on a space in the team. It's a tough decision to hear for any player with everyone hoping they have worked hard enough to make it but ultimately there are only 23 places available for each team.
Matthews will now be forced to sit back and watch the Euros as a spectator though as he prepares for a new season, for which his future is certain. Whether he will be involved in Sam Allardyce's plans as he aims to take Sunderland away from constant relegation battles remains unclear, with there rumours of a permanent switch to Bristol.
The game with England will be one of the biggest in the nation's history and that will make missing out even tougher for Matthews.
