The job Neil Harris has done at Millwall has been remarkable, with his side really impressing on their return to the Sky Bet Championship.

Ahead of this season not many people held much hope for Millwall back in the Championship, but Harris’ side have defied expectations and really excelled.

Millwall still have hopes of finishing in the play-offs this season, which would be a remarkable achievement for Harris and all involved at the Den.

Whether Millwall have enough to secure play-off football during the run-in remains to be seen, but there is so much for the club to take out of this season and into the 2018/19 campaign.

Harris will know the summer will be a vital one for Millwall, who can’t afford to sit still and must improve on what they have done this season.

With that in mind, we look ahead to the summer and identify THREE Harris decisions that could define Millwall’s 2018/19 campaign…

Gregory has been magnificent for Millwall this season, leading the line with real purpose.

The striker has scored plenty of goals on his second-tier return, which could lead to some interest from elsewhere.

Millwall need to tie Gregory down to fresh terms and secure his long-term future.

Harris is putting together a really good squad at the Den, but in the summer, quality needs to be prioritised over quantity.

Bringing the right men in next season could really help to take Millwall’s squad to the next level.

Millwall’s form in 2018 has been superb, with Harris’ side right at the top of the form table after an excellent start to the calendar year.

Over the summer, Harris needs to make sure that Millwall carry their current momentum into the start of next season, as a fast start could put them on course for another memorable campaign.
