After shocking everyone and competing for the play-offs last season, Millwall are a team to watch this term.

Teams are going to have to start taking Millwall more seriously after they defied all expectations to push for promotion to the Premier League, rather than fight against relegation.

Neil Harris has worked wonders with his Millwall squad and there is a real sense of optimism that something special is brewing in South London.

The Lions play simple but effective football, with a deadly combination of short and long passes, quick tempo and crosses into the box.

Millwall fans will be hoping that they can carry their momentum into next season and launch a real promotion push.

This week is vital for Millwall as it is the final week of June.

Once July starts, the new season is just around the corner and preparations for the 2018/19 campaign will be well underway.

Here are three things we expect to happen at Millwall this week.

Millwall players are due back in pre-season today, other than injured defender Sid Nelson and World Cup star James Meredith.

Many of the club's younger players and those on the periphery of the squad will be hoping to make a quick impression this week as Harris decides who to sell, loan or keep.

With Australia likely to be heading home at the group stages of the World Cup, Cahill will enter negotiations over a potential stay at Millwall.

The 38-year-old re-joined the club in January and Millwall are hopeful of keeping him.

Millwall could make a real statement this summer by completing a club record signing of Marshall.

The 27-year-old winger impressed on loan at Millwall last season and Wolves do not want him so a £1.25m capture would be ideal for Harris.
