Will Jack Harrison stay with New York City FC or go to Stoke City?

Yet, the English forward is still in preseason camp in Jacksonville, Fla. with the Major League Soccer side, so perhaps he is going to stay, says head coach Patrick Vieira.

“There is a possibility for him to stay, the same way there’s a possibility for him to go,” Vieira said in a conference call Wednesday. “But at the moment he’s here, he’s working really hard and I’m really pleased with the way he’s been conducting himself the last two days, but Jack has always been good.”

The English Premier League team reportedly has raised its offer from $4.5 million to $7 million for the 21-year-old Harrison.

Vieira, however, wouldn’t discuss transfer possibilities, saying that it was sporting director Claudio Reyna’s territory.

“It’s a question for Claudio,” he said. “Since we are here, all my focus and concentration is on training the team. To try to improve every aspect of their game, so we can be ready to play against Kansas. That’s my only concentration. Jack is here and working as hard as everyone else.”

Harrison is coming off his best MLS season, having recorded 10 goals and six assists.
