Given the referee didn't have the benefit of 17 (slight exaggeration) different camera angle replays, his decision for the Targett / Fabregas incident was perfectly valid.The decision to not award a penalty can't be called 'wrong' or 'bad' as his interpretation was based on what he saw in real time. Another referee might have interpreted it differently, which would have been equally valid. Referees are human and as such, borderline naked eye decisions are always going to be subjective. One thing's for sure, we wouldn't be having this debate if replays didn't exist.
