Arsenal have already made their first move in the summer transfer window, bringing in Gabriel Martinelli from Ituano.
But supporters will be hoping the £5.3million Brazilian is not the only capture.
Director Josh Kroenke has told supporters to "be excited" about what is to come in the transfer window - words that could come back to haunt him if Arsenal do not sign their targets.
The Gunners believe they have a deal in principle to sign William Saliba from Saint Etienne, although the 18-year-old defender would go back to France on a season-long loan.
And the transfer has not yet been completed, with Tottenham also trying to sign him.
Meanwhile there remain talks over a move for Celtic full-back Kieran Tierney, with two bids already rejected by the Scottish champions.
Arsenal take on Bayern Munich in the International Champions Cup in Los Angeles tomorrow morning and during his pre-match press conference, head coach Unai Emery was asked about incoming players.
And he revealed how many deals the Gunners want to complete in the coming days.
He said: "Our target is to get three or four players who really improve our squad now. We are being very, very demanding and first speaking about the possibility to sign very expensive players. The first player in our list is our first target, if we cannot achieve that the second.
"We are waiting for two, three, four players to help us and also with everybody creating a new way with a lot of positive things we worked on last year. We need to take the best players in some positions, really being demanding of ourselves for these players.
"Really I can say to our supporters we are going to make a very good team with the players there now and three or four players who can help us in a few days."
