Play a 4-3-2-1 formation
Spurs have a very solid midfield and with Dele Alli suspended, we can expect Moussa Dembele to drop into the central midfield role, adding more venom and grip to it. They’d be a more physical side than they would’ve been if Alli would’ve started in that position. To add an extra man in the midfield, and to provide extra cover to Cesc Fabregas in the central midfield area, playing a 4-3-2-1 formation would make some sense. This would help Chelsea to deny Spurs much space to control games in the midfield and would also make it tough for Dembele to bulldoze past the players easily. The move would squeeze up some space that Spurs can use to create opportunities from the middle third and play snappy and slick football in those areas.
The move would also grant the likes of Willian and Hazard more freedom to operate behind Diego Costa, who will be sole man forward.
