Doncaster Rovers manager Darren Ferguson says new signing Danny Andrew will give him more flexibility this season.
Andrew will work with Ferguson for a second time, having spent three years with him at Peterborough United.
“I am really pleased to get him over the line, he is our second signing of the summer and he gives us the flexibility that we were missing last season,” said the Rovers boss.
“He is left-footed and can play left back, left wing back and left centre half as a three where he played for Fleetwood, him and Enda Stevens were the best left backs in the league last season.
“We did not have enough balance in that position, we were playing with a right-footed left back throughout the majority of last season, Tommy Rowe was also filling in, now Tommy can play more centrally.”
Andrew played 50 games for Grimsby in all competitions last season, which included two league games against Rovers.
“When we played Grimsby he was the one that was the real threat and he is a danger at set pieces, which is important, and his left foot was pivotal for us signing him,” added Ferguson.
“He’s moved on since the last time I managed him, played well in League One at Fleetwood Town - a couple of injuries knocked him back, but he’s recovered from that really well."
