Middlesbrough boss Gareth Southgate hopes fans do not burst their FA Cup dreams by taking balloons to Bramall Lane on Sunday.
A stray balloon from Manchester City fans saw Michael Ball mess up a clearance, which resulted in a Sheffield United goal on their way to a 2-1 fourth-round win.
Boro boss Southgate said: "We can get 5,000 fans there and it'll be great to get that level of support, but no balloons please!"
