Dennis Greene admitted he was ‘concerned’ after watching his Boston United side get knocked out of the Lincs Senior Cup.
Mark Jones and Jon Williams netted for Trinity in their 2-0 victory at York Street.
“It was pretty disappointing, I thought they were better in all departments,” the manager said.
“The lack of composure on the ball, the lack of creativity.
“We didn’t get close enough to their players and didn’t react quick enough off the ball.”
However, Greene did believe that Trinity should have been down to 10 men after Tom Ward’s foul on Ricky Miller.
The ex-Pilgrim brought the forward down as the last man, but referee Wayne Porter amazingly gave nothing.
“It should be a sending off. He’s brought him down as the last man,” Greene added.
“But the referee didn’t really give us a lot all game to be fair.
“We had one or two opportunities to get back in the game but we didn’t take them.
“I think it was a concern. Today should have been an indication of where we’re going to be this year, we’re playing a Conference North side.
“No disrespect to Gainsborough, I’d say they’re probably seventh or eighth, around that area.
“We were second best so it is a concern.”
