The 36-year-old joined on a free transfer from Paris Saint-Germain in the summer with Frank Lampard keen to add experience to his defence.
However, the Brazilian made a mistake during his debut on Saturday as he was at fault for West Brom’s second goal in the 3-3 draw at The Hawthorns.
Lampard is adamant that Thiago Silva will be a key part of Chelsea’s defence but concedes his inability to speak English could be a ‘slight barrier’.
‘Thiago will be a very, very good player for us,’ Lampard said after the draw with West Brom.
‘He doesn’t speak the language very well but that’s just something we will have to work through. It is what it is but I’m not sure how relevant that is to the game.
‘There are players here that can speak the languages that he can, with French being the main one. But we also have lads here that can speak Portuguese and Italian, which Thiago can, and they can interact with him.
‘If the language is a slight barrier then we will need time to work on that, and that is what we have in front of us.
‘People will want to talk about his mistake and that’s fair, it comes with the nature of being the top footballer that he has throughout his career.
‘But at the same time, other than that one moment, we saw just how good he is. We saw his leadership skills, his quality and I think we are going to see more of that as the season progresses.’
