Speaking on BBC Sport while covering Wednesday's game, Theo Walcott said: "I've said this numerous times recently, I think the argument about Arsenal's lack of prolific goalscorer will rear its ugly head again.
"I am a big fan of a certain Brentford forward [Ivan Toney]. But it is one of those. Arsenal are a really big team, but with all the set pieces, if you've got someone like that in your team you are an even bigger threat.
"There was no Gabriel Jesus, so Arsenal didn't really have anyone else to call upon. Kai Havertz as good as he has been recently, he is not a striker either. That is something that Edu and Mikel Arteta will be discussing in the summer."
With Jesus sidelined with yet another injury, Leandro Trossard lead the line for Arsenal away at Porto in the Champions League on Wednesday night.
However, a lack of a proper striker hurt the Gunners as they ended suffering a 1–0 defeat ahead of the return Round of 16 clash at the Emirates next month.
