I very much agree that Lerma was lucky to escape without a yellow card in the first half. It could be argued he'd have ended up with a red as he did finally get booked 2nd half, but he'd probably not have committed the foul he got booked for if he was already on a yellow.
Otherwise Bankes was inconsistent, his foul detection is very random and at times it was difficult to work out what was or wasn't a foul, however he was as equally poor and inconsistent for both teams. Not the best day at the office, it has to be said.
