Neil Harris has described a "rollercoaster of emotions" as the summer transfer window continues ahead of the new Sky Bet Championship season.
The Lions have made two summer signings so far, with Ben Amos joining Murray Wallace and the rest of the squad in Portugal for the club's pre-season training camp.
The manager told millwallfc.co.uk that whilst the club are trying to improve with incomings - wanting "one, if not two, more," there may also be outgoings before the campaign gets underway with the visit of Middlesbrough on Saturday 4th August.
"We've made bids for players. It's been well publicised that we missed out on Ben Marshall and whilst we won't talk about other teams' players, we want to try and improve. We're trying to add quality.
"There's going to be some players come August that want to get out the door and play some football, whether that be on loan or permanently. They're great lads - it's hard to say no when they come to me, I just want them to be happy.
"If we can bring one, if not two, more into the group - it's a rollercoaster of emotions in the transfer window, because one minute you think you've got a deal done and then the next minute, it's been scrapped."
