Middlesbrough boss Tony Mowbray has suggested that Leicester City's first goal may have been offside.
Boro were beaten 2-1 by City despite leading and dominating for much of the first half of their Championship clash.
"There's a hint of offside about their first goal," Mowbray told reporters. "We were good value for our lead. But that second goal just didn't happen."
Boro have now failed to win in 12 of their last 13 opening matches of the season.
