A lucky win for Chelsea FC over 10men fulham calls for check. Chelsea has being struggling all along with the Coach unable to set his path right.

Lampard has to understand the different between A System and tactics. Almost all coaches has their various system which they operate with but the difference is the ability to tweak the system when the need arises.

For example Conte came with a 3-4-3 system which he is known for but sometimes tweaks the system to 3-5-2 depending on his opponent and even sometimes make a player to switch his position.

Sarri came with his pattern of laying stronghold of Jorginho to form a kind of football pattern which keeps the ball but sometimes uses Hazard to tweak the system when odds arises.

Lampard uses 4-3-3 system which is very good but he inability to infuse different tactics to his system is showing and opponent have understood this and that is why he is having issues.

Full backs overlapping and creating chances, chillwell was assisting scoring

The two 8s attacking the box at intervals, wingers cutting inside

Kante shielding the back four, we played some good football that period

All these you listed are tactics. A teams system are specific tactical instructions given to players, instructing them on how to operate both in the attacking phase and defensive phase.

Tactical instructions are given to players to enable them understand how to use a system or playing method.

I hope Lampard finds a way around it and I wish him the best. Blues for life.
