26-year-old centre back, Jon Guthrie, came on as a second half substitute in the win at Oxford City, and started the match at Thame United.
The defender was released from Walsall following the clubs relegation to League Two last season, where he made 101 appearances for the Saddlers, scoring four times in just two seasons.
Prior to that, Guthrie spent five seasons at Crewe Alexandra, one of which was in League Two, where he made 137 appearances, scoring once.
At 6 ft 3 in, he is commanding in the air, and powerful in defence. The defender can also cover at left back.
Exeter born Elliott Frear was another to feature in the win at Thame, where he had a goal ruled out for offside.
The 28-year-old began his career with the his hometown club where he made twelve appearances, but spent time on loan at Tiverton Town and Salisbury City.
Following his release from Exeter, the winger signed for Salisbury permanently, where he made a further 43 appearances in one season.
From there, he signed for Forest Green Rovers of the National League, where he made 123 appearances, scoring thirteen.
His performances sparked a move to Scotland where he signed for SPL side, Motherwell. During his time north of the border, Frear made 74 appearances, scoring eight.
It was when scouting new U’s signing, Alex Gorrin, that Karl Robinson noticed Frear. The winger impressed, as he did at the ASM Stadium, and Robinson said: “When we were looking at Alex, Frear was someone who really stood out.
Despite suffering relegation, Guthrie could be a useful addition. Much of his career has been spent consistently in League One, and after Curtis Nelson left to join Cardiff City, the U’s are in need of some solid defenders.
Frear is slightly different, given his game time in England has been in the lower leagues. That said, he’s impressed during his time with Motherwell, and would probably cope. The U’s have lots of options on both wings, but being a naturally left-sided player could swing it in his favour.
