League One transfer latest: Ex-Tottenham and Leeds midfielder joins Port Vale

All the latest summer transfer news from League One...

It's been a tough summer for Port Vale. They've already lost Doug Loft, Jennison Myrie-Williams, Jordan Hugill and Joe Davis this summer, and on Friday they were served with a winding-up order by Revenue and Customs. However, that didn't stop manager Micky Adams bringing in three new midfielders, as former Tranmere Rovers man Steve Jennings, ex-Rotherham United midfielder Michael O'Connor and Michael Brown - formerly of Tottenham Hotspur and Leeds United - all arrived at Vale Park.

"We're delighted to bring both to Vale, they're two vastly experienced players," said Adams on Brown and Jennings. "The club have created some good competition for the midfield places and I'm excited about the coming season. I'm sure the fans will like what they see when Michael [O'Connor] plays because he's an all-round midfield player," Adams added. "He can pass, he can score goals and he's really competitive as well."

Elsewhere, MK Dons strengthened their squad again with the signing of Brentford striker Will Grigg. The former Walsall man hit 20 goals in 46 games for the Saddlers in the 2012/13 season, but struggled to make and impact at Brenford last season. With the Bees now in the Championship and looking to sign Rochdale's Scott Hogan, they've allowed Grigg, 23, to move to Milton Keynes on loan for the season.

"I'm absolutely over the moon. He's the one I've wanted for the last 12 months," MK boss Karl Robinson told the League One club's website. "When he played against us for Walsall, I thought he was an outstanding talent. He's a name at this level, he's a goalscorer at this level and he's a Northern Ireland international too. He's got the pedigree to come in and do well."

Meanwhile, Barnsley's bid to return to the Championship at the first attempt has taken a hit as star striker Chris O'Grady has finally left the club. The 28-year-old target man has been strongly linked with both Charlton Athletic and Sheffield United this summer, but it's Sami Hyypia's Brighton who have signed him for an undisclosed fee, with Argentine hitman Leonardo Ulloa set for Leicester City.

"He is a strong, physical presence." Hyypia said. "Chris gives us something different to the other strikers we already have here at the club."
