Emery confirmed that Ollie Watkins "will be ready" despite picking up a knock while with the England national team.
On the excellent performances of Morgan Rogers performances for the Three Lions: "He is getting better. He started [the season] a bit like the team - not performing well and not confident. But in the last matches he has played, he might not be scoring but he is playing better."
The Villa boss suggested the environment with England has helped Rogers improve: "It is helping him with the national team how they were performing collectively and individually. He is responsible and a protagonist like he is in the starting XI [with us]."
He said "every match we are facing is very difficult" when asked about the challenge posed by their hosts, adding: "Tottenham is one of the contender teams to be in the top seven. Last year they didn't achieve it but this year they are playing fantastic. Getting good results, now at the top with 14 points and playing at home they are feeling strong."
He continued: "For us it is a huge challenge."
Emery emphasised the importance of Tottenham qualifying for the Champions League this season and praised Thomas Frank for his start as manager: "He is doing very good work like he did when with Brentford. He deserved to get something more and now he has opportunity and challenge, and Tottenham is now one of best in Premier League. In the stadium with their supporters and with new tactics, they are a very, very strong team."
