Blues academy graduate Mount enjoyed a breakthrough season under Frank Lampard in the 2019/20 campaign and has continued to produce consistent performances this term.
The England international scored a vital winner against struggling champions Liverpool on Thursday night to fire Chelsea into fourth place in the table.
And Oscar, who played for Chelsea for four-and-a-half years before joining Chinese Super League side Shanghai SIPG in 2017, was full of praise for Mount.
‘I like him,’ Oscar told talkSPORT of Mount.
‘Sometimes he doesn’t play like me but sometimes, I watch him and I can see a little bit of me there because I also came into Chelsea when I was so young and played good football.
‘I really like him. He has everything you need to improve.
‘He scores goals, he does some important things and he knows how to defend and attack. I really like him.’
‘I think about finishing at Chelsea because I had good times before at Chelsea,’ Oscar added.
‘Chelsea helped me a lot to improve and to do what I always dreamed [of], which was to play in the Champions League and they helped me to play in the World Cup and to win the Premier League.
‘I have a lot of friends at Chelsea. If I have a chance to finish my career at Chelsea, it’s a dream for me.
‘Of course, Chelsea don’t like to buy too many older players, which is normal because it’s a top team from Europe, but I will try my best to be fit to finish there.’
