Paul Hurst's men had firmly established themselves as League One promotion candidates, and with both momentum and a sell-out crowd behind them, the Shrews were determined to add another chapter to what is already turning out to be a decent campaign.
"I was a substitute against BATE Borisov in a Europa League game and I was called to get stripped to come on - but I didn't have any shinnies".
Shrewsbury were by far the more vigorous side, robust in the tackle and dynamically mean with the amount of space offered to their supposedly superior opponents.
Hart made his first competitive appearance against his home-town club as West Ham clinched on to a goalless draw in the FA Cup third round tie at Montgomery Waters Meadow. After Cheikh Kouyate failed to get a telling touch to a unsafe cross by Cullen in the ninth minute, any whiff of a first-half breakthrough by the away team vanished.
"They looked stronger than us".
Joe Hart kept West Ham in the FA Cup after the Hammers survived a scare at his old club Shrewsbury.
"I am very grateful, we have one in the kit van but Aaron Cresswell's hair is that bad that apparently at the last game he took it and he's rocking the Umbro cap", he smiled.
And Shrewsbury-born Hart admitted he needed help in the first half.
England global Hart was tested by Shaun Whalley and Mat Sadler, while the Premier League side mustered just four attempts at goal - only two on target - at the New Meadow.
Mat Sadler's shot in the 35th minute packed much more power and demanded a solid save from Hart, who had to repeat it moments later when Alex Rodman let fly from a similar position at the left-hand corner of the West Ham box. You're only talking about 30 seconds - and they sent on Shoky!
Midfielder Jon Nolan could have clinched a famous third-round win for the hosts but fired over late on, while the Hammers, playing their third match in six days, only managed four shots.
