Everton could be without Sandro Ramirez for their Europa League play-off tie with Hajduk Split on Thursday evening.
The Spanish striker, who joined the Toffees earlier this summer from La Liga side Malaga on a five-year deal for a fee of Â£5.3million, is a doubt for Ronald Koemanâ€™s side.
The 22-year-old had managed to play 77 minutes of their Premier League tie with Stoke City on the opening weekend, however, he suffered a knock to his heel and had to be replaced.
Sandro has not been able to participate in training sessions, however, Koeman is prepared to leave it until the last minute to see if he can feature in any way.
â€œSandro got a knock on his heel last Saturday and we need to wait until tomorrow [Thursday] to see if he will be available,â€ the Dutch boss told the club’s official website.
â€œHe did not train on Wednesday and if it is not better, he will not play. It is not really serious, the question is more yes or no for tomorrow â€“ but, normally, there will be no question for Mondayâ€™s game against Manchester City.â€
Koeman has also revealed that James McCarthy remains unavailable after he picked up an injury to his knee during a training session.
Problems to that particular area of the body seem to have become a big issue for the Goodison Park players, with many having already been sidelined due to their occurrences.
Ramiro Funes Mori has been confirmed to miss the majority of the season, with a return thought to be around April, whilst Yannick Bolasie is also nursing a similar problem.
Experienced right-back Seamus Coleman continues his recuperation from the broken leg he suffered while on international duty back in March.
Ross Barkley, who has been heavily linked with a move away from the Toffees this summer â€“ especially with the news of Gylfi Sigurdssonâ€™s arrival all but confirmed, will not feature against the Croatian outfit, as he looks to start the road to recovery from a pulled hamstring he picked up in training.
