This time last year, Marc Guehi had never even played in the Premier League.
Now, the Crystal Palace defender is celebrating a maiden call-up to the England senior team after a fine debut campaign in the top flight. Guehi has taken nicely to life with the Eagles. His call-up by England boss Gareth Southgate, himself a former Palace centre-half, is testament to the 21-year-old's rise to prominence.
Despite being on the books of Chelsea for 14 years, a large part of his development came in two concurrent loan spells with Championship side Swansea City. That is the place where Guehi got regular football and showed not only an obvious defensive knack but an ability to play out from the back - a prerequisite in recent years for Swansea.
