It's far too simplistic to think that simply by having wingers it will make it easier to break teams set up like this down.
Reading you could see worked incredibly hard and their wide men were coming so far back that they effectively became full backs and the full backs tucked in which congested the middle.
I thought we got in behind a number of times but failed with the final ball or shot, had we got the goal the game would have opened up, we didn't, hence it became a game of attrition.
The good thing is we still won the game, but we have to become more clinical when chances/openings present themselves. This is where the rags are better than us IMO.
As for Rekik, he did well, but you could tell that left back was not his natural position but under the circumstances he did a good job for the team.
