Young and Warnock called up by England for Euro qualifier
Young has been in stunning form for Villa in his new role as a second striker, wowing crowds with his dynamic displays in claret and blue.
Houllier has switched Young to a positon just behind the central forward and the 25-year-old has certainly excelled.
As well as his standout performances, he is also Villa's joint top scorer, after finding the net against Bolton, Blackburn and Wolves.
Warnock has been solid and reliable as always at left-back and will be thrilled to return to the squad, after missing out on the three internationals since his World Cup involvement.
Bolton forward Kevin Davies is called up for the first time by Capello, joining Darren Bent, Peter Crouch and Wayne Rooney among the attacking options.
In midfield Jack Wilshere has been named in both the senior squad and Stuart Pearce's England U21s.
Capello's men take on Montenegro at Wembley on Tuesday October 12 in their third qualifying game ahead of the finals in Poland and Ukraine.
The Three Lions beat Bulgaria 4-0 at Wembley in their first match and Switzerland 3-1 in Basle in their second and will be looking to make it a hat-trick next week.
