Shamrock Rovers withstood plenty of early pressure as their 3,000 travelling fans made plenty of noise and forced a delay to the game when streams of white ribbon were hurled towards Christopher Nkunku at a corner, but it was a defensive blunder that saw them fall behind after 22 minutes when MK Dons loanee Darragh Burns attempted to head Renato Veiga’s long pass back to his goalkeeper, but got it all wrong as Guiu nipped in to head home from close range.
