That's a fantastic delivery from Topley. Left-arm angle pushing it in to Shakib, he played as if it's going to hit middle and leg but with that movement, it hits the very top of off.
Topley really was happy with that one, it was an absolute jaffa.

That is a big wicket. Shakib played all round that and loses his off stump.
Bangladesh are really in the mire. Reece Topley has taken three big wickets.
Shakib b Topley 1 (Ban 26-3)
Bowled! That is a beauty!
Reece Topley is a man on fire right now. He has his third wicket and it is the Bangladesh captain Shakib, Topley's delivery too good for him, with Shakib playing that one everywhere but where the ball was.
Bangladesh three down early on here.
Target 365
Woakes ends with two dot balls, two tidier overs from him after an expensive start to the day.
Topley will return at the other end. Two wickets in his first over and a review in his second. What will the third bring?
Jonathan Agnew
BBC cricket correspondent on Test Match Special
Woakes is asking for trouble there. Full and too wide and eased through the covers for four.
Very well put away by Liton Das.
Target 365
Three dot balls start the over, but Woakes' attempts to tease Das with a slower ball backfire, and the Bangladesh opener cracks a delivery for four.
We're only a few overs in, but already, Das looks very settled.
Target 365
Having conceded a boundary with his first ball of the over, Topley keeps it tidy, conceding just one run from the remaining five deliveries.
England will be pleased with the early pressure they have been able to put onto their opponents.
As Steven Finn said, it pitched outside leg. A wasted review for England, who have just one left now.
That would have been a massive wicket, if that review was successful.
Steven Finn
Former England bowler on BBC Test Match Special
It looks a bit leg side and all the players are dispersing now. They've seen one replay and that's enough.
It pitched outside leg.
England review. Topley's delivery hits Das' pad, although it looks like there may be some bat involved.
The umpire is not interested, but England take it upstairs.
Target 365
Not a pleasing start to Topley's second over as Das clips the ball fine to find the boundary.
He already has for fours to his name.
Jonathan Agnew

The ball dribbles back and almost onto the stumps. When things are going your way, that hits but it's all a bit of hard work for Woakes at the moment.
Target 365
Better from Woakes, with just three runs coming from that over.
The final ball of the over almost dribbled onto the stumps after Shakib fails to get it away, a nervy moment for him.
Liton Das' time in the middle seems important after those two early wickets. He hit three fours in as many balls in the first over.

Dan: Chris Woakes cementing his reputation as the nicest man in cricket by giving Bangladesh a chance to win this game.
A bit harsh, Dan. We've all bowled the odd expensive over in our time...
Target 365
No hat-trick for Topley, who found Shakib's pad, but it was quite a way down the leg side.
What a start from Topley, just two runs conceded and two wickets in as many balls for him and England.
Chris Woakes will be hoping to build on Topley's start after an expensive first over from him.
Steven Finn
Former England bowler on BBC Test Match Special
That was a smart catch from Liam Livingstone, the ball would have raced to the boundary if it had beaten him.
Jonathan Agnew
BBC cricket correspondent on Test Match Special
Perfect start for England. It's not just about beating teams like Bangladesh, Afghanistan and the Netherlands, they have to beat it well because of the net run-rate.
Hossain Shanto c Livingstone b Topley (Ban 14-2)
Two in two!
Topley is on a hat-trick as Livingstone takes a sharp catch at point.
A wider delivery from Topley, Hossain Shanto does not get enough of it and it is an excellent start for England.
