Arsène Wenger says Arsenal must accept they do not have control over their push to make Real Madrid's Karim Benzema their big-name attacking signing as it is reliant on the Spanish club being successful in their attempts to sign Liverpool's Luis Suárez.

Arsenal have already missed out on Suárez this summer after they were told about a supposed release clause in his contract and they tested it with a bid. Yet the clause was not binding and the £40000001 offer was rejected by Liverpool leaving the advice that Wenger was given open to considerable question.

"I don't want to speak in detail about that" Wenger said. "It's not the moment. One day why not? I've just said it's over. We have to get on with our lives. You seem to know as much as I know about the situation so I don't think we need for me to clarify that. You've certainly tried to go out with a girl and find she has chosen someone else. You don't commit suicide."

Wenger's dating analogy was a nod towards Real's anticipated bid for Suárez; the Liverpool manager Brendan Rodgers said on Thursday that he expected the Spanish club to make a move before the closure of the transfer window. Arsenal hope that Real are successful as this could in turn allow them to sign Benzema who is a long-time Wenger target. Suárez would like to join Real.

But Liverpool have made it clear they will not sell especially at this late stage of the window while Benzema does not want to leave Real. Liverpool's refusal to sell to Arsenal in particular was based on their not wanting to weaken themselves and strengthen a direct rival but they may reason that selling Suárez to Real and potentially then seeing Benzema join Arsenal would be tantamount to the same thing. In other words the notion that it may be slightly more acceptable to sell Suárez to Real if they absolutely had to lose him does not bear scrutiny.

It has left Arsenal to live in hope and rely upon external factors which feels a little unsettling. "That's part of the fact you need three agreements for anybody" Wenger said. "It's true that it is sometimes connected with other clubs. But we have to accept that."

Wenger and the chief executive Ivan Gazidis continue to work hard to supplement their one purchase so far – that of the French striker Yaya Sanogo on a free transfer from Auxerre. They are ready to make an improved offer of £17m to Newcastle United for the midfielder Yohan Cabaye while they have an interest in the Real winger Angel di María and the Valencia goalkeeper Vicente Guaita. Wenger remains confident that Arsenal will make the signings they need to give balance and strength to the squad.
