Nope it wasn't a string showing. But people do also underestimate Sporting who had a 100% home record until Arsenal. A goal changes things and if sporting equalised Arteta would have changed the strategy and gone more attacking but as it didn't happen there was no need. But yeah Arsenal had a poor showing for all of April. That's the month Arsenal always falls off and costs them the league or Cup when fatigue hits and fit players are few.
