Chelsea have confirmed their second signing of the summer. The Stamford Bridge club have announced the transfer of young Dutch midfielder Marco van Ginkel, from Eredivisie club Vitesse Arnhem for an undisclosed fee; the BBC believes this is in the region of £8m.

A statement on the Blues' website reads: "Chelsea Football Club and Vitesse Arnhem have reached an agreement for the transfer of Marco van Ginkel. The player will join Chelsea subject to a medical, agreement of personal terms and legal documentation."

The 20-year-old van Ginkel scored eight goals from 33 games last season, helping Arnhem to fourth and gain access to the qualifying stages for the UEFA Europa League. Chelsea beat Premier League champions Manchester United to van Ginkel; David Moyes reportedly had scout Jim Lawlor monitor the player during the European U21 Championships in early June.

The young Dutchman, rated as one of the brightest talents in the Netherlands, becomes the second new face in west London, for the start of Jose Mourinho's second spell in charge. The first was German international Andre Schürrle, who signed for £18m.

Marco van Ginkel's signing may affect Chelsea's pursuit of Serbian international Nemanja Matic. The 24-year-old Benfica star is believed to be a target for both the Blues and Real Madrid but the Portuguese club are expected to stand firm on their £42m valuation, making any deal a potentially difficult one for either interested party.

Meanwhile, as Schürrle and van Ginkel arrive, another German midfielder, Marko Marin, leaves Stamford Bridge, albeit on loan. The 24-year-old signed in a £7m deal last summer but injuries meant he failed to establish himself in the team and made only 16 appearances (five starts) all year, with a goal and an assist to his name.

And in a bid to help him regain form, fitness and confidence, Chelsea have allowed the former Werder Bremen star to join Spanish side Sevilla on loan.
