Why Arsenal should be very wary of Newcastle United in the League Cup semifinalsNewcastle United pose a significant threat to Arsenal in the League Cup semi-finals. The Magpies have a strong recent record against the Gunners, having won three of their last six meetings. They also reached the League Cup final two years ago and have a lethal talisman in Alexander Isak, who is the Premier League’s fourth-top goalscorer. Arsenal could be without key attackers Bukayo Saka and Raheem Sterling due to injuries, which could give Newcastle an advantage.
