Chelsea have completed the signing of Netherlands midfielder Marco van Ginkel from Vitesse Arnhem on a five-year contract, the Premier League club said on Friday. “I am a box-to-box player. I cover a lot of metres and can score a goal, but I also like to defend and think of myself as a real team player,” Van Ginkel told the west London club’s official website (www.chelseafc.com). The 20-year-old came through the youth system at Vitesse Arnhem before making his debut in the Dutch top flight towards the end of the 2009/10 season aged 17. He got his first cap for the Netherlands in November when he came on as a substitute against Germany and also played at the European Under-21 Championships in Israel last month. Van Ginkel scored 11 goals in 41 games last season and helped Vitesse finish fourth and qualify for the Europa League.
