The Premier League is looking to add a fresh face to the squad, with former West Ham midfielder Danny Rose expected to be selected to fill in for injured midfielder Andy Carroll.
Rose, who scored 26 goals in 71 appearances between 2009 and 2015, will join former West Bromwich Albion and Stoke City defender Alex Song on the West Ham bench.
Rose has been on the bench since his return from a hamstring injury in the FA Cup fourth round replay against Manchester City on Monday.
Rose will join fellow former West End star, ex-West Ham player and former England striker David Ospina in the new team, which will be comprised of players who have previously played for West Ham.
West Ham are also keen to secure the services of midfielder Kevin Nolan, who has made just seven appearances for the Hammers this season.
Nolan joined West Ham from Bolton Wanderers in the summer of 2015 and has made five appearances for his new club.
Celtic’s James Forrest, who was a late replacement for injured striker Craig Gardner, is also on the list of West Ham players to be included in the squad.
Celtic were the surprise winners of the Europa League last season after finishing runners-up to Tottenham Hotspur in the group stages.
Fixtures against Tottenham Hotspurs and Sunderland will be played on Tuesday, December 17, with Celtic facing their former Premier League opponents for the first time in their history on Saturday, December 20.
