The managers now face a tough home game against a much-rejuvenated Reading side, who have climbed to 16th in the League One table. Ahead of the crucial fixture, we look at all the major headlines surrounding Portsmouth’s League One rivals.Former Reading captain signs short-term deal with League One rivals.League One new boys Northampton Town have agreed to sign former Reading captain Liam Moore on a short-term deal until the end of the season. The 31-year-old has been without a club since being released by Reading in June 2023, shortly after the club were relegated from the Championship.Moore trained with the Cobblers for several weeks before the move and was praised for his impact by manager Jon Brady. Brady told the club’s website: “He has already fitted in well with the group and brings a wealth of experience and a great pedigree.”Moore started his career at Leicester and was loaned out to Bradford City, Brentford and Bristol City at a young age. He joined Reading in 2016 and reached the Championship play-off final in his first season.He was named club captain in 2019 and made a total of 234 appearances for the club before leaving last summer. He could return to face Reading when the teams meet on Friday, March 29.Derby manager hails ‘pretty good’ away performance as they ramp up pressure on Portsmouth.Derby kept their place in the automatic promotion places with a 3-0 win against in-form Exeter City. Goals from Max Bird, Nathaniel Mendez-Laing and Tom Barkhuizen sealed the 11th away win of the season.Assistant head coach Richie Barker praised the team’s performance and the way they adapted their style away from home. He told the club’s website: “Obviously we are very happy with the result and the players did what we asked of them, which was a bit different away from home. Sometimes you have to win matches in a different way.”We gave the ball away a bit tonight where Exeter got the ball in certain areas hand and then pressed. We saw that with Max Bird’s first goal. We pushed a little differently and everyone had to buy into it. You’re only as strong as your weakest link, and if one goes out, it won’t work.We worked yesterday on the training ground and today in the team hotel, so when you see it pay off and score a goal, it’s a good feeling. We didn’t have much time to work with it and had to accumulate a lot of information in a short time to make it even better and worth the effort.“Birdy was very successful in achieving his goal because he is a smart boy and takes great pride in his learning and listening skills. He received his award, as did the team. They all understood the importance of playing like us. Was it a perfect performance? No. Was it good enough hosting? I think so.”.
