Chelsea have confirmed the squad which has traveled to Croatia to face Dinamo Zagreb in the Champions League.
Michail Antonio’s opener was deemed to be illegal by Tuchel, who believes that an offside should have been awarded before the corner in which the Hammers scored.
Ben Chilwell equalized off the bench before Kai Havertz netted what turned out to be the winner, also making an appearance as a substitute.
West Ham thought they had equalized moments later through Maxwel Cornet but for VAR to intervene and suggest the referee to review the footage.
After watching replays on the pitch-side monitor, Cornet’s late equalizer was ruled out as Jarrod Bowen was adjudged to have fouled Edouard Mendy, leaving the Irons furios.
Despite starting every match so far this season, Thiago Silva is absent from the squad to travel for the Champions League opener.
N’Golo Kante has also not traveled due to a hamstring injury sustained against Tottenham Hotspur earlier this season.
New signings Pierre-Emerick Aubameyang and Denis Zakaria make the squad and could be in line for their Chelsea debuts.
Wesley Fofana could be in line for his second start after his debut against West Ham.
The Blues will be hoping to get a win in their first match of the competition.
Chelsea have flown out to Croatia ahead of the match, with Tuchel taking a 23-man party with him for the match.
