Redis - Do I need to have sentinel when clustering is there?

I have a working Redis sentinel setup already (master, slave and 3 sentinels). I am planning to set up a redis cluster with 3 masters & 3 slaves.

Can I get rid of sentinel set up when I have redis clustering? If not how would the set up look like?

You don't need Sentinel when using Redis cluster.

Redis Cluster perform automatic failover if any problem happens to any master instance.

From Redis Essentials book:

Redis Sentinel and Redis Cluster share a lot of characteristics, but each has its own goal. Sentinel's goal is to provide reliable automatic failover in a master/slave topology without sharding data. Cluster's goal is to distribute data across different Redis instances and perform automatic failover if any problem happens to any master instance.
