Dinamo Zagreb will have no injury worries when they line up to the clash against the Irons on Thursday evening.
They warmed up in style against seventh placed Sibenik with a 2-0 win at the weekend to retain their place at the top of the Croatian League table.
The game saw the return of skipper defensive midfielder Arijan Ademi who has been absent for six weeks, centre back Rasmas Lauristen for just over a month who appeared in the second half and attacking midfielder Marko Tolic after two months.
All came through unharmed and will be involved in the clash against the Hammers as we start our assault on the Europa Cup.
The Hammers have no injury problems and it will be interesting to see whether the manager goes with new signing Kurt Zouma or give him his debut against Manchester United and presumably Ronaldo.
Possible Hammers team: Areola; Coufal, Zoumas, Ogbonna, Cresswell, Rice, Soucek, Bowen, Fornals, Vlasic, Antonio
Dinamo: Zagorac – Dilaver , Theophile, Šutalo – Špikić, Mišić, Ivanušec, Moubandje; Tolic , Petkovic- Juric .
