Lucas Paqueta scored for West Ham in their 3-1 win over Chelsea - just days after Mail Sport revealed he was the subject of an FA probe into potential betting breaches, although he denies the allegations.
Hammers boss David Moyes named Paqueta in his midfield alongside a debuting James Ward-Prowse, as the club looked to build upon their draw with Bournemouth in the Premier League opener last week.
Meanwhile Moyes' other senior signing of the summer, former Ajax star Edson Alvarez, was named on the bench, although the Mexican was introduced late on.
