How will the Europa League loss impact title challenge for Arsenal?

Arsenal's Europa League exit could be a blessing in disguise, or could it have an impact on their Premier League title challenge for the title?
Mikel Arteta believes Takehiro Tomiyasu is in "pretty serious" condition after the Arsenal star left Emirates on crutches. William Saliba was also taken to the Emirates with what appeared to be a back problem.
Arteta described "disappointment" but also "clarity" as they strive for their first Premier League title since almost 20 years. Arteta currently leads the Premier League by five point. Will this affect Arteta's side? Or will it be a blessing with title ambitions in sight, as suggested by Martin Keown, ex-defender?
"We didn’t win enough duels at certain spots. We didn't apply enough pressure to the ball. Arteta stated that we gave the ball away frequently and it created an open game that we didn't want.
Arsenal is disappointed, but it begs the question: Is this a blessing? Does it impact the momentum? I don't think so. He told BT Sport that there were a few injuries, so it could have been a costly defeat."
"The Premier League is so large that they can now go at it wholeheartedly. Arsenal want to keep Manchester City, but it shouldn't surprise us that they have fallen foul of all the changes [against Sporting].
He only needed one glance to see Aaron Ramsdale off his lines before executing a pinpoint chips that flew over the back-pedalling goalkeeper and into the very small space he could possibly find the net.
It was a goal that brought back memories of David Beckham's famous lob against Neil Sullivan for Manchester United in 1996 against Wimbledon. You can also refer to the Nayim for Real Zaragoza effort from the halfway line that contributed to the Gunners' defeat in the 1995 Cup Winners Cup final.
Keown said to BT Sport that he can't help but think he would have looked. He knows Ramsdale sets high goals, but the execution was exceptional. He doesn’t even look up, it’s sublime, a magnificent effort.
Nick: It's a shame, but it could be a blessing in disguise. Arteta's insistence on making too many changes has cost us tonight. We don't have enough second string to do that yet. He should remember that he is not at Man City anymore.
Fqiren: Arsenal gets a fantastic result. It wasn't going be enough to win it anyway. Champions League football, which was their main goal this season, is now more or less secured through the league. They can save their bodies for the 11 finals.
Paul: I wanted us to win, so we put together a team to win, but we weren't good enough. Although losing may help us with the title challenge, that's not what we came here for. We wanted to win, but we lost, so it's a failure.
