Wellens ran the rule over eight trialists during the 4-0 win, with the goals coming from two of those handed minutes.
Here, we take a look at the octet who featured at Oxford Street.
1. Aidan Barlow
The former Manchester United youngster played on the right of a front three in the first half - and certainly made an impact. A hat trick in the opening 45 minutes ensured a scramble to find out exactly who Rovers were handing an opportunity to. The 21-year-old struggled to get involved in the early stages but settled into a groove, working off the shoulder of the last man to pounce on opportunities.

2. Nathan Thomas
Back on trial with the Rovers for the second time after being invited in last year. He played in the second half on the right of the front three but managed on 11 minutes before being forced off with injury.

3. Aramide Oteh
Played as the central striker in the second half. Showed a good turn and powerful driving runs. He won a penalty when clipped by the Rossington keeper and stepped up to fire home confidently.

4. Dan Gardner
The former Chesterfield man played on the left of the front three in the first half and got on the ball well, linking with Tommy Rowe. The 31-year-old is a free agent after leaving Wigan Athletic at the end of last season.
