Peterborough give the ball away cheaply in midfield and they're queuing up on the left but Charlie Savage's effort is blocked.

The oles are coming out now from the travelling Reading fans.

Free-kick Reading.

You'd expect Robbie Savage to have had a word with his team at half time. Taking nothing away from Reading who played the opening 45 minutes really well, but it was men against boys in the first half.

He'd have told them to compete better, pass the ball better, and Peterborough had a good spell after the break.

A flowing move from right to left and Reading have a good chance to make it 4-0.

The opening goalscorer, Daniel Kyerewaa, leans back on this occasion though and finds the stands rather than the top corner.

That really would have been it, still with half an hour to go.

Reading's half-time sub Ashqar Ahmed is booked for a pull back.

It's a great delivery from the left but when the ball is knocked down, too much indecision from two Peterborough players on the edge of the box means the chance to get a goal back quickly goes.

Peterborough have the opportunity to put the ball in the box from a free-kick but Reading deal with the situation.

Changes for both sides now. Matthew Garbett is off and on comes Danny Ormerod for the hosts.

Reading make two subs as well. Jack Marriott and Kyreece Lisbie are withdrawn, on come Jamie Reid and Randell Williams.

Reading break forward and Charlie Savage looks to lob Alex Bass but Bass does well to tip the ball over the bar for a corner.

A plethora of substitutions to tell you about as Robbie Savage reverts back to a back four.

James Dornelly, Liam Kelly and Vernon Masara are all on in place of Lucca Mendonca, Harry Ashfield and Ethan Williams. Robbie Savage was clearly unhappy with his side's efforts in the first 45 minutes.

Reading have made a change at the break too. Ashqar Ahmed is on for Udoka Godwin-Malife who picked up a knock following a foul from Williams in the first period.

We are back under way and Peterborough have a mountain to climb in this second half.

I didn't think there was much in the game until the first goal. After that they really tried to put their foot down and kill off this tie before half-time.

Charlie Savege's goal is all about him seeing the danger, holding his run, letting it run across his body and finishing. Reading are deservedly in charge of the game, and Savage has been superb.

Reading in total control of this one as the home side are booed off by some portions of their own supporters.

The Royals have been in ruthless mood so far. German forward Daniel Kyerewaa opened the scoring after some nice interplay outside the box moments after Peterborough had gone close to grabbing the first goal of the game.

Jack Marriott converted Haydon Roberts' pinpoint centre to double the visitors' lead before Charlie Savage scored his first goal of the season, against his dad's club, to make it 3-0 at the break.

Reading have one foot in the second round already.

Kyreece Lisbie tries to get in behind for Reading but Harley Mills makes a crucial interception at the back for the hosts.

It's all very last-ditch for Posh.

There will be four minutes of additional time at the end of the first half meanwhile.
