Goalkeeper and captain Dan Bachmann is back in the squad to face Leicester tomorrow, but head coach Valerien Ismael admitted he was concerned that so much detail about the player’s head injury found its way into the public domain.

Bachmann missed the 5-0 win over Rotherham before the international after being concussed in training, but resumed training this week after working closely with club doctors and medical staff.

“Dan is back in the squad,” Ismael said.

“We followed all the concussion protocols and we have been given the green light by the medical department that he can join back in with the team.

“Our medical team did a great job, working and following all the protocols, and I know Dan feels much better and confident.

“We still have another session today to assess him, but the signs are all really good with Dan.

“He lost consciousness and because of that you have to follow set rules, and that included him being out for seven days.

“Then we he came back we had to steadily raise the volume of each training session for him.

“Because of the international break we had two weeks to work with him and take all the tests he needed which enabled him to get the green light from the doctor.”

Ismael said he was aware that details of Bachmann’s injury, some of which were inaccurate, were being discussed on social media.

“That was medical information that should be secret, and for sure the information did not come from us,” he said.

“The people who share that sort of information in the outside need to be very careful, as it is a medical matter and that sort of thing is private.

“Normally it isn’t possible to speak about someone’s health unless the other person has agreed and is ready to speak about it.

“I understand people are interested in that sort of information, but we have to deal with these topics properly and respect protocols.”

There was mixed news of the other players who missed that Rotherham win due to injury.

“Sierralta has been back in training for two days now. He’s fit and now we just need to assess if it’s enough for the game,” said the Watford boss.

“The only big issue we have is with Ngakia. He was sick which was why he missed the last game, but we also thought he had a slight problem with his ankle.

“He had further examinations and we found that he had a stress fracture in his ankle.

“So he has had surgery and will be out for a couple of months.”

Other than the Ngakia setback, Ismael has a full squad to utilise and said the break away from league action had been useful.

“It was a good break and we worked well, although it was a smaller group because more players were away on international duty.

“The good news is everyone arrived back punctually and healthy, and in a good mood.

“The attitude and intensity in training had been great because, as you can imagine, the confidence is there and we have momentum on our side.”
