#1 Real Madrid's high press
Though not the finished product, Real Madrid did plenty of pressing in the opposition half, led chiefly by Gareth Bale and James Rodriguez. It yielded a couple of good chances in the first half and is likely to be a tactic Real Madrid will use again in the future.
For most of the first half, the Welshman and the Colombian chased down everything they could, joined in part by Karim Benzema as well. It saw them create a couple of chances against a resilient Sevilla defence.
More importantly, the press subdued some of the attacking impetus of the home team with Reguilon and Navas pinned back.
Should they be able to bring a little more organisation to it and start to lay down pressing traps, they could build it into a cohesive pressing unit that they could deploy when required.
