Manchester United youngster Saidy Janko has been given international clearance to join up with his new club and could make his first appearance in the UEFA Youth League clash with Real Sociedad.
The Switzerland Under-19 international signed for the club on transfer deadline day, a move that remained relatively below the radar as United sought to finalise deals for players capable of coming straight into the first team.
After impressing United coaches during a summer tournament, the Premier League champions moved quickly to secure the right back's services and after finally been given the green light to move to Manchester, the teenager could make his first appearance for Nicky Butt's side against the group leaders, with Sam Byrne also in line for a return.
"Saidy is cleared," Butt told United's official website. "He is available and in contention. He played against England Under-19's last week on the right hand side. He's a good talent and we're all excited about him. He has a good presence and goes about the game the right way.
"Sam is okay and training again now. We'll just take a look at everybody and pick the team tomorrow. We've got a big squad now as the younger lads from Paul's (Paul McGuinness, United's Under-18 head coach) group are proving they are more than capable of playing at that level."
Butt's side currently sit third in their group after suffering a 2-1 defeat to Shakhtar Donetsk last time out, while the Basque outfit have fared far better than their senior counterparts, sitting top after thrashing Bayer Leverkusen 5-1 a fortnight ago.
"Obviously, we're aware they're a good team," Butt added. "We've had them watched and saw the DVDs. They're a typical Spanish team, they are not giants but all smallish lads, and they move the ball and manipulate it well.
"They have got two or three outstanding players so it's going to be a big challenge to us."
