Some players travelled to Spain with existing injuries specifically to continue their rehabilitation and did not feature in the fixtures, others were omitted for precautionary measures, while goalscorer Raul Jimenez was withdrawn early in the 3-0 win over Besiktas.
Chakraverty said: “Pre-season is always a balance between trying to give players the preparation they need to be ready for the season, and also knowing when to protect them.
“If someone is feeling a symptom, we will give them an assessment, and if we withdraw them from training or a match, that will be an agreement between the coach and the medical team, depending on the level of risk that we are prepared to take.
“For example, if someone is feeling their hamstring, even though they may not be injured, it is a risk factor, so sometimes we choose to protect them and keep them out of the games.
“An example of this is Toti, who was feeling his hamstring after the second game, and we didn’t want to take a risk on him. Chem Campbell was in a similar situation and has now been cleared to train again.
“Similarly, Matija Sarkic felt some upper hamstring pain in training and was aware of it on certain movements, so we decided to protect him while we give it some time to settle. A scan on Monday revealed nothing serious and he will re-join training next week.
“Earlier in the camp, Hee Chan Hwang felt a pain in a small muscle around his hip whilst shooting. He maintained his fitness throughout the camp and resumed training this week.
“Raul came off in the game against Besiktas after he stretched for the ball and felt something in his knee and his groin. Scans reveal that he has suffered a medial collateral ligament injury to his knee and a minor strain of his adductor. Neither injury is very serious but he is expected to be out for a number of weeks.”
Three members of the travelling pack headed out with the squad to Spain to continue their rehabilitation, while Chiquinho remained back in Wolverhampton to undertake surgery having sustained a knee injury during the friendly win over Burnley at the start of July.
Chakraverty explained: “Adama Traore has a small hamstring injury picked up before the team travelled to Spain, but is progressing well.
“Nelson Semedo is also doing very well in his recovery from the hamstring injury he sustained against Brighton, at Molineux, on 30th April. He should be back training with the squad after we return from Portugal.
“Jose Sa was injured in the final game of the season against Liverpool, a medial collateral ligament injury to his knee. He has returned to full training and is expected to feature soon.
“Chiquinho underwent knee surgery following injuries to his anterior cruciate and lateral collateral ligament injuries. The surgery went well and he is now back in Wolverhampton recuperating.”
