Millwall enjoyed a brilliant first campaign back in the Championship last season that almost saw them sneak into the play-offs.

A superb 2018 will have given everyone connected with the Lions a real sense of optimism about what next season could hold, although it's clear Neil Harris will need some new faces.

The Londoners have a very good first XI however there are question marks about the depth should they suffer with injuries or suspensions.

They've also been dealt a huge blow with Norwich closing in on Ben Marshall, the Wolves winger who was instrumental to their second half of the season after joining in January.

However, there are still plenty of options out there to improve the squad and here we look at THREE potential signings that could improve Millwall...

The Lions have been linked with the stopper and he would be a good signing. Despite their good season, keeper Jordan Archer made far too many basic errors.

Therefore, it's vital he has some serious competition and Amos would provide that.

Millwall have done very well with transfers from Wolves over the past 12 months and they should go back for winger Graham from the Premier League side.

He has electric pace, is an out and out winger and would put real quality into the box. He may need to improve defensively to suit Harris' 4-4-2 but when he adapts he could become a star in the division.

It may be tough to convince QPR to sell but under new management Smith may not fit in at Loftus Road.

However, he would be ideal for Millwall. They are direct in their play and the huge striker would cause all sorts of trouble and also scores goals.
