Unai Emery has given Nicolo Zaniolo the start against West Ham United in the Premier League.
The Italian Football Federation is now conducting an inquiry into the winger’s potential illicit betting behaviour.
However, like with Newcastle United’s Sandro Tonali, Zaniolo is still eligible for selection, and the summer signing has been given a chance in the final third.
The sole change from the 1-1 draw with Wolverhampton Wanderers before the international break is Zaniolo starting on the wing.
Diego Carlos has already been relegated to the replacements’ bench, and it is uncertain whether Emery would use a midfield trio with John McGinn on the right wing and Moussa Diaby in the centre.
Meanwhile, West Ham manager David Moyes has stuck with the team that started the 2-2 draw with Newcastle United.
Mohammed Kudus would have hoped for a starting spot after scoring as a substitute against Newcastle, but he has yet to make his Premier League debut.
West Ham trail their sixth-placed hosts by two points going into the game in the West Midlands.
