article: Jack Grealish must concentrate on his Aston Villa career rather than his international future, according to Tim Sherwood. Sherwood has been impressed with the 19-year-old who starred for Villa in their FA Cup semi-final win over Liverpool on Sunday and is now at the centre of a tug of war between the Republic of Ireland and England. But Sherwood wants Grealish to focus on continuing to force his way into the Villa first team. Jack Grealish takes on Liverpool's Emre Can at Wembley during Aston Villa's 2-1 victory at Wembley . Grealish (centre) impressed against Liverpool and is wanted by the Republic of Ireland and England . 'It’s up to Jack where he wants to go. It’s purely up to him. What I’ve got to do is make sure he’s got that decision to make. He must be doing something right for Aston Villa if he’s got those options. That’s my priority,' Sherwood told talkSport. 'Then it’s up to Jack to decide where he wants to go. I had the same situation with Nabil Bentaleb [at Tottenham], who could have played for France but decided to pick Algeria. I did have a chat with him and he asked me what to do. I just said: "you’ve got to go with your heart. Do you think you’re French or Algerian?" 'That’s the decision he had to make and now Jack has got to make that decision. He has to play a few more times for Aston Villa before he needs to make that decision. When some kids come and play with the first team sometimes, they’re a bit overawed, but Jack’s not. 'He receives the ball and dribbles it around people. They kick lumps out of him because he’s so confident. The ball is his friend, it sticks to his foot. The more opportunities he gets, the better he’s going to become.' Grealish is expected to choose between Ireland and England at the end of the season and Sportsmail understands that he is split between the two countries at the moment. Grealish's dad Kevin agreed that his son must concentrate on his club football first. 'That is fantastic [advice]. He had a good game against [Liverpool] and a few games decent recently and he has to keep doing that first and the international stuff will come,' he told talkSport. 'It is going to be a difficult decision and it is completely up to Jack. 'There is a friendly coming up soon and he could play 45 minutes for Ireland and 45 minutes for England.
