Newcastle have completed the signing of forward Siem de Jong from Eredivisie champions Ajax.

The 25-year-old Holland international moves to Tyneside for an undisclosed fee and has signed a six-year deal at St James' Park.

De Jong came through the Amsterdammers fabled youth system and has won four Dutch titles since making his debut in 2007, assuming the captaincy in 2012.
