The visitors are going through a sticky patch themselves, with Sunday's 1-1 draw with Nantes representing their third top-flight game in a row without a win.
Marseille president Jacques-Henri Eyraud reportedly tore in to the Olympiens squad after their Ligue 1 title hopes took yet another blow in a 2-1 home defeat to relegation-threatened Nimes at the weekend.
The words "pathetic" and "rubbish" were allegedly used to describe Andre Villas-Boas's men by the infuriated president, who had witnessed his team succumb to a quickfire double from Niclas Eliasson before Dario Benedetto pulled one back for Marseille.
In fairness, Villas-Boas's men would have undoubtedly been feeling some fatigue from their Trophee des Champions defeat to Paris Saint-Germain, but with only one win to show from their last six in Ligue 1, it is clear that multiple problems must be addressed.
Marseille still have two games in hand over the five teams above them in the table, so all is certainly not lost, but they can only rise as high as fourth should they win them both with Lyon, Lille and PSG all out of sight.
Les Olympiens' dismal defeat to Nimes was only their second home defeat of the 2020-21 Ligue 1 campaign since losing to Saint-Etienne back in September, although they have failed to keep a clean sheet at the Orange Velodrome all season.
After playing out a 1-1 draw with a Nantes team who have found their resolve under Raymond Domenech, Lens have now gone three games without a win for the first time in Ligue 1 this season.
Gael Kakuta rescued a point for Franck Haise's men with his eighth goal of the season after Imran Louza's penalty had put Les Canaris ahead, with that result extending Lens' winless run in the New Year after an impressive first half of the season.
Not many supporters would have placed bets on Lens challenging for a European berth in their first season back in the big time, but having won just one of their last five, a spot in continental competition may be a step too far for Sang et Or now.
In fact, Lens are the only team in the top half of the table who have failed to win any of their last three matches, and they are at risk of being leapfrogged by Montpellier and Brest should they fail to get the better of Marseille this week.
A coronavirus outbreak in the visitors' camp prevented this fixture from being played when it was supposed to last October, and Marseille will be aiming to win their fifth game in a row against Lens when the two sides lock horns on Wednesday.

Marseille's midfield resources are depleting further by the week, with Boubacar Kamara being forced off after only 18 minutes against Nimes with an apparent muscular problem.
The 21-year-old's injury is not thought to be serious but he will most likely miss out here, while Villas-Boas has confirmed that there is Premier League interest for Morgan Sanson, who is being linked with a move to Aston Villa.
Steve Mandanda could return in goal for Yohann Pele if he shakes off a minor injury in time, but Jordan Amavi's continued absence could see Yuto Nagatomo line up at left-back once more, with new arrival Pol Lirola ineligible for this rescheduled game.
Marseille possible starting lineup:
Mandanda; Sakai, Balerdi, Caleta-Car, Nagatomo; Gueye, Rongier; Thauvin, Cuisance, Payet; Benedetto
Lens possible starting lineup:
Leca; Medina, Gradit, Haidara; Clauss, Fofana, Doucoure, Boura; Kakuta; Sotoca, Ganago
We say: Marseille 2-1 Lens
Marseille would have been handed a harsh wake-up call with that damning assessment from their president after the loss to Nimes, and Villas-Boas's options for change are wearing thin with a growing number of players injured, suspended or heading for the exit door. However, Lens have endured a similar run of pitiful results and will struggle to assert any sort of dominance at the Orange Velodrome, so we think Marseille will make an immediate return to winning ways in a closely-fought contest.
