I’m sure Silva can still do a job at the back, but at the age of 38, he’s very unlikely to be playing the same kind of part he is now in two or three years’ time," said Collymore.He added:“If they’re looking to give him an 18-month extension, fine, but it should be with a view to him transitioning into a more mentor or coaching role, to help bring through whoever is going to be the club’s long-term centre-back pairing."He continued:“I just think his presence in the first team is now starting to hinder the younger players and their development. I’d love to see a Chelsea team in two years’ time with a couple of 22-year-olds at the back and who knows, one of them could go on to be the next John Terry."Silva has appeared 23 times across competitions this season for the Blies and has set up two goals.Chelsea submit enquiry for Dani OlmoDani Olmo (right) is wanted in the Premier League.Chelsea have submitted an enquiry for Dani Olmo, according to Fichajes via Caught Offside.
