Everton manager Marco Silva has revealed that Yerry Mina has been in full training all week ahead of their clash with Arsenal on Super Sunday.
Mina is yet to make his Everton debut due to a foot injury and Silva refused to confirm whether the Colombian international would be involved against the Gunners.
"Mina is working with the team, for the full week until now," said Silva.
"He's getting better every day, getting in good fitness as well."
Silva also confirmed that Seamus Coleman, Phil Jagielka and Andre Gomes would be unavailable for the trip to the Emirates, but that some were returning to training.
"Some good news, some of the injured players have started full training with the squad," he added.
"We keep the same situation with Jags, I think next week he'll start with the squad. Gomes is still out and it's the same situation with Coleman."
Everton will be boosted by the return of Richarlison following his three-match suspension, and Silva was pleased to welcome back the Brazilian.
"He's an important player for us," he said. "He started the season very well, scoring important goals to help the squad. It's good news for us that he's able to play now."
The Everton boss said that while the trip to Arsenal will be "tough", he expects his players to put in a good performance.
"It will be tough for us for sure, but we will have to play at our best level and to complete at that level is something you have to do," he said.
"Of course it will be tough. What I want is to see our players compete at that top level, working hard and performing well if you can to achieve a good result."
