Kyle Walker says Pep Guardiola can only do so much for Manchester City and that it is ultimately down to the players on the pitch to deliver.
The City boss has not won the Champions League since leaving Barcelona in 2011 and has not got beyond the quarter-finals since he joined the Premier League club.
However his side are strong favourites in Saturday’s last-eight clash with Lyon, although Walker warned that they can’t any afford any errors if they are to get past the Ligue 1 side that knocked out Juventus in the previous round.
