On the Shaheen and Bumrah comparison, this is pointless. Neither have played 30 tests and bumrah is on the decline.
So Shaheen staying fit he will easily surpass bumrah - it’s not rocket science it’s just simple logic
What's with this Bumrah on the decline nonsense. He was crucial in England and picked 18 wickets in a competitive Indian bowling attack which had Siraj & Shami also picking up wickets. We are not a one bowler team like Pakistan. Shaheen might pick up more wickets and also be bowled to the ground by Pakistan team management as none of the other bowlers look anywhere close to threatening when playing overseas. India have a good all round attack and we don't have to bowl Bumrah too much. India uses Bumrah in short spells like the Oval game where he bowled those 5-6 overs in the middle to break the back of England batting.
Yeah his ODI record has decline over the last 2 years but his Test bowling hasn't been that bad. India have competent 4 man pace attack at most times, so he cannot be picking 5 wickets every time he plays. He has 8 fifers in 29 Tests which is very good with 3 of them coming in last 12 months. Shaheen in 24 Tests has 4 which is 4 less than Bumrah in just 5 less Tests.
