Liverpool manager Jurgen Klopp criticised the "dry pitch" at the Hawthorns after his side were held to a draw against West Brom in the Premier League.
The Baggies staged a dramatic comeback to earn a point but they could still be relegated on Sunday.
The hosts were 2-0 down after 79 minutes - Danny Ings and Mohamed Salah on target for the Reds - before goals from Jake Livermore and Salomon Rondon.
"It was a difficult game as the pitch got drier and drier," Klopp told Sky Sports.
"West Brom decided not to water the pitch at half-time and that makes it difficult.
"It makes a massive difference. A team like West Brom do not need a wet pitch, they can do it next year playing on a dry pitch in the Championship."
West Brom caretaker manager Darren Moore said the pitch "was not a tactic" and was "the same for both teams".
"It was a hot afternoon - we watered the pitch before the game," said Moore. "The heat has dried out the pitch."
West Brom's comeback started when Livermore scrambled home at a corner for his first goal at the club before Rondon headed in Chris Brunt's free-kick in the 88th minute.
Salah had earlier continued his brilliant form with a chipped second-half finish which takes him to 31 Premier League goals this season and sees him equal the record for a 38-game campaign.
Liverpool, who made five changes to their starting line-up with their Champions League semi-final on Tuesday in mind, were ahead after just four minutes through Ings.
The Englishman, who was making just his second start under Jurgen Klopp, stroked home from six yards for his first goal since October 2015.
The draw ensures Moore extends his unbeaten start in charge of West Brom but they remain bottom, eight points from safety with three games left.
