Stoke City boss Tony Pulis has questioned West Ham United's deal for Demba Ba.
The Potters rejected the former Hoffenheim striker over a failed medical before West Ham stepped in.
"If he'd been close to being OK we would've signed him," said Pulis, who has seen Ba, 25, score three goals in four games.
"But the medical reports we had showed there was a massive risk. Luckily for him and West Ham, nothing's happened.
"However, we could've lost him after a training session and the money Hoffenheim wanted was unreasonable."
