Manchester United's Antonio Valencia resigned to summer exit - sources

Antonio Valencia is resigned to leaving Manchester United in the summer after the club decided against triggering a one-year extension option in his contract, sources have told ESPN FC.

United had until 5 p.m. on Friday (March 1) to inform Valencia -- still club captain at Old Trafford -- that his deal had been extended until 2020, but the deadline was allowed to pass without the 33-year-old receiving notification.

United caretaker manager Ole Gunnar Solskjaer told a news conference earlier on Friday that Valencia could earn a new contract if he could regain full fitness after spending the past two months recovering from a calf injury.

However, sources have told ESPN FC that the Ecuadorian expects to leave Old Trafford at the end of the season. He is not thinking about retiring and will consider his options before deciding his next move.

Writing on Instagram, Valencia appeared to address rumours over his future by speaking of his pride to represent United for a decade.

He said: "Lago Agrio is a very humble town in Ecuador. When I was a child, I never imagined [to] travel to Europe. Thanks to God for letting me play 10 years in the best club in the world: Manchester United. Now I am focused on my recovery so I can end the season playing at Old Trafford."

Valencia will be entitled to a testimonial in the summer, but scheduling a tribute game would be complicated by his departure. He is closing in on 350 appearances for United and has won six major honours, including the Premier League title in 2011 and 2013.

He featured in 31 of United's 38 league games last season as Jose Mourinho's team finished second behind Manchester City, but injury problems have seen him lose his place at right-back to Ashley Young.

Long-term replacement Diogo Dalot, 19, was signed from Porto in the summer.
