Paul Merson slated Chelsea's performance against Nottingham Forest
However, Pochettino's project will take time as he attempts to stamp his mark on a completely new squad full of young players. Chelsea's starting XI against Forest had an average age of 24.5, and there is nobody better than the 51-year-old to guide their development. Pochettino will be confident of finding a winning formula and bringing his attractive style of football to Chelsea, but he won't be naive. After spending a record amount of money in the summer transfer window and already passing the £1bn mark under the ownership of Todd Boehly, he'll know the club's hierarchy will want to see clear improvements sooner rather than later.
