The duo have been a key part of Millwall’s team over the past two years, and both played a pivotal role in Millwall’s promotion from League One in 2017, scoring a combined 37 goals.
When they depart The Lions will be left with only Tom Bradshaw and Tom Elliot as their striking options, which means new faces will have to arrive at The Den.
It is important that Neil Harris brings in similar replacements. Both Morison and Gregory suited his style of play perfectly so he should target players who will be able to perform a similar role.
We look at three replacements Millwall should go for to improve next season.
Marquis is an unsurprising addition to this list, given that he has played for Millwall before and been linked with the club already this summer.
He never really impressed in his first spell at the club but at Doncaster he has grown massively as a player, and is now one of the most prolific strikers outside the Championship.
He is also a Neil Harris player, he works tirelessly and is strong in the air, particularly when it comes to meeting crosses. His finishing has improved drastically in the last couple of years and he can now score all types of goals – with both feet too – which would make him a key asset next season.
In order to replace Gregory Millwall need a harrying attacker who will work tirelessly in closing down defenders, and Godden can provide exactly that.
Added to that, Godden knows where the goal is too, he scored 35 goals in two years at Stevenage before joining Peterborough, where he scored 18 last season, proving he could adjust to the step up in quality and still be as efficient.
He has a real poacher instinct and is great at pouncing all loose balls in the opposition penalty area, which is a similarity to Gregory.
The downside for Millwall is that he won’t come cheap. Peterborough have already turned down a bid from Portsmouth believed to be around £500,000, and with two years still to run on his contract he could fetch a price close to the £1m mark.
The 27-year-old is another striker who’s career appeared to be stagnating before he arrived at Gillingham and transformed into a real goalscorer.
Prior to that Eaves based his game on his physical attributes, and he was mostly a problem for defenders due to his aerial presence and ability to link up play.
Those attributes have remained, but now Eaves has developed into a brilliant finisher, with both feet and head. There is probably no better striker outside the Championship better at attacking crosses than Eaves, making him ideal for Millwall.
The Lions had a lot of success with set pieces last season, and a player like Eaves would thrive off the service from Shane Ferguson, and he could be Millwall’s for nothing as his contract is up at the end of June.
