Arsenal were held to a 1-1 draw by Fulham in the Premier League on Sunday.
They missed a huge chance to cut the gap between them and Liverpool at the top of the table after the Reds had their game against Everton postponed due to bad weather.
The Gunners went behind after Raul Jimenez opened the scoring in the 11th minute. They levelled through William Saliba before Bukayo Saka had a late goal ruled out after VAR ruled Gabriel Martinelli offside during the build-up.
Having scored both of their goals in the 2-0 win over Manchester United on Wednesday from corners, Arsenal continued to threaten from set-pieces at Craven Cottage, with Saliba scoring after Kai Havertz headed the ball back across goal following a corner.
The team have exploited the height advantage in their team to score from set pieces, but pundit Gary Lineker is worried about their over-reliance on them.
“My concern, a little bit, about Arsenal is they are not quite scoring goals without those set pieces,” the former England international said on the latest episode of the Rest is Football podcast.
“And they did not create too many opportunities yesterday.”
The Gunners have bagged 22 goals from corners since the start of last season – more than any other Premier League club – and their rivals are starting to work on how to stop them.
Fulham came very close yesterday but eventually succumbed, and Arsenal must improve creatively in the final third.
While their set pieces have proven effective, they cannot always rely on them.
