Christian Atsu
Another attacking midfielder in a squad packed with them, Chelsea have perhaps done the wise thing in loaning Christian Atsu out immediately after purchasing him. The £3.5m signing from Porto has been highly impressive in the Portuguese league, attracting interest from the likes of Liverpool and Tottenham as well, though the Blues did well to snap him up late on in the transfer window. He will now spend the season on loan in the Eredivisie with Vitesse Arnhem, and looks like another good investment in youth by Mourinho, again for a bargain price.
Not a player who will make an impact this season, but another who makes the future look bright at Stamford Bridge. 6.5/10.
