The Blues are seven points clear at the top of the Premier League table as Chelsea look to get over the line in the title race despite coming under pressure from Tottenham Hotspur.
Conte signed Kante in a £30m deal from Premier League champions Leicester City back in July before the Chelsea manager recruited Alonso from Serie A outfit Fiorentina.
Moses, meanwhile, was included in the Italian’s first-team plans after being out-of-favour under Jose Mourinho and enduring loan spells at various Premier League clubs.
Former Chelsea defender Desailly credit Alonso, Kante and Moses with helping to transform the west London side since his appointment as Guus Hiddink’s successor.
“I’m very pleased [with Chelsea],” Desailly told Sky Sports News HQ.
“When you look at last season where it was very difficult with [Jose] Mourinho in charge, a whole lot of controversy and the tactics were not working, this year you change it and have three new players: (N’Golo) Kante, (Marcus) Alonso and (Victor) Moses and you just change a little bit of the tactics, it’s just an amazing season for Chelsea.”
Chelsea signed five players in the summer transfer window in 2016.
The Premier League leaders will make the trip to Manchester United in their next game at Old Trafford on Sunday afternoon.
