Millwall are looking to do some substantial business in the transfer window.

The Lions secured an 11th place finish last term but will no doubt be hoping to kick on next term as they push towards as potential play-off position.

If they're to do that then Gary Rowett's side will need to strengthen - something that they're clearly looking to do according to reports.

As per Belgian outlet GVA, via Nottinghamshire Live, Millwall have been credited with an interest in Groningen midfielder Ahmed El Messaoudi.

The 25-year-old scored eight goals for the Dutch side last term and as a result is said to be attracting interest from Championship rivals Nottingham Forest as well.

Should a move to the Den materialise, here are 2 knock-on effects that the club must consider.

Winner Jed Wallace

Millwall have perhaps been a little bit too reliant on Jed Wallace in recent seasons.

The right-sided player scored 10 goals and picked up seven assists last term but was often isolated as the club's main creative threat under Gary Rowett.

With Ahmed El Messaoudi having a track record of scoring goals from the middle of the park it could be great news for Wallace who can look forward to having his workload eased.

Loser - Ben Thompson

The central midfielder could be the victim of the new arrival.

Ben Thompson has just one year on his deal with the club and after being limited to just 16 starts last term there's a question mark over his long-term future at The Den.

While pre-season will dictate how things will pan out, there's a chance that Thompson could be pushed further down the pecking order by such an arrival.
