London, April 27 -- Arsenal are back on top of the Premier League, but Mikel Arteta claimed their title challenge could be ruined by two rejected red card decisions in their games against Manchester City and Newcastle. Arteta's side are three points clear of second-placed Manchester City after Eberechi Eze's early strike clinched a vital 1-0 win against Newcastle on Saturday. But the Gunners boss was frustrated with the decision not to send off Newcastle goalkeeper Nick Pope for a foul on Viktor Gyokeres in the 74th minute at the Emirates Stadium. Pope raced out of his penalty area to clatter Gyokeres, escaping with a yellow card because the Sweden striker was wide on the right wing without a clear sight of goal. With the prospect of goal difference potentially deciding a gripping title race, Arteta knew Arsenal would have had a chance to rack up a bigger win if Newcastle were reduced to 10 men. Instead, they had to settle for a result that left them only one goal better off than City in the goal difference column. Arteta was also still harbouring a grievance from last weekend's crucial 2-1 defeat at City, when Abdukodir Khusanov wasn't sent off after hauling down Kai Havertz. The Spaniard believes those two decisions could prove decisive in settling the title race. "I don't know why the Newcastle keeper wasn't sent off. I have seen it 10 times. If you have ever watched football, you know it was a red card. These are the margins," Arteta said. "I am saying the reality of the last two games, in crucial moments with everything at stake, we need things to go our way. I'm not making excuses. "It was a red card today and a red card in Manchester. If they go our way we are in a different world today." Arteta's rant underlined the mounting tension at the Emirates as Arsenal chase a first English title since 2004. City's 1-0 win at Burnley in midweek had knocked Arsenal off top spot for the first time since October, raising the spectre of another title race collapse after their blown leads in 2023 and 2024 gifted the trophy to Pep Guardiola's men. Arsenal had lost their previous two league games and four of their last six in all competitions. Once again, they struggled to impose themselves for long periods against Newcastle, but Eze's superb strike from a well-worked short corner was enough to settle their nerves....
