Sixth-placed Portsmouth visit Stadium MK to take on MK Dons this Saturday, with three points an absolute necessity for the visitors. After stringing together four wins in a row, Portsmouth have failed to win their last two outings. With Charlton Athletic and Oxford United hot on their heels, Portsmouth have to keep winning to retain a spot in the promotion playoffs.Home side MK Dons, on the other hand, are sandwiched in the middle of the League One table and don't have all that much to play for. Yet, it is unlikely that the Dons will be in a charitable mood come the weekend, especially given that they are playing at home.Also Read: Manchester United forward Edinson Cavani has told the club he wants to leave - ReportsMK Dons vs Portsmouth head-to-headEllis Harrison's strike from the spot separated these two teams in the reverse fixtureThe two clubs have battled only seven times before, owing to the fact that MK Dons were founded in 2004, over a century after Portsmouth came into existence.MK Dons have only won one of those seven matches while managing to eke out two draws.MK Dons form guide: L-D-L-W-WPortsmouth form guide: D-L-W-W-WMK Dons vs Portsmouth team newsMK Dons⚪️ x 🔵A look at those who have played for both #MKDons and Saturday’s opponents Portsmouth 👉 https://t.co/JqA0fo1gss pic.twitter.com/CSHcy8FgbA— Milton Keynes Dons (@MKDonsFC) April 15, 2021Manager Russell Martin was extremely annoyed with how his team performed in their last match, when they were humbled 4-0 by Lincoln City. It was also their third game in a row where they failed to score. A strong reaction is necessary. However, they'll need to do that in the absence of top-scorer Cameron Jerome, who is set to miss the next few games due to injury.Injuries: Ben Gladwin, Warren O'Hara, Cameron JeromeDoubtful: Louis ThompsonSuspensions: NonePortsmouth📰 John Marquis saw a second half penalty saved as #Pompey were held to a 0-0 draw at Crewehttps://t.co/D4GDQRDib6— Portsmouth FC (@Pompey) April 13, 2021Portsmouth will be without Michael Jacobs for the rest of the season after the winger injured his knee against Wigan.
