Conceding three away goals gives Shamrock Rovers a lot of work to do next week in the Czech Republic, but they are still in with a shout of progressing in Europe courtesy of two Graham Burke strikes.
The Hoops ultimately lost 3-2 to Czech outfit Mladá Boleslav, and Rovers boss Stephen Bradley admitted that he was disappointed with coughing up two of the three goals.
"I was very disappointed with the third goal, and the first one. The second one to be fair was a good bit of skill by their midfielder."
"Obviously it deflates you a bit but the one thing we didn't do is give up as a group."
A Golgol Mebrathu goal for the visitors in the 34th minute was cancelled out by a Graham Burke wonder strike 14 minutes later.
Bradley was full of praise for a special goal and special player on an up and down night in Tallaght.
"It was an unbelievable strike. Graham lets it run across his body, takes a touch, then another touch and then sticks it in the top corner from 30 yards out but I thought all night his performance was different class.
"He was so clever in possession, he brought us into the game, he was brave. He got on the ball in areas that you need to be brave to get on the ball in and I thought he was excellent throughout."
Rovers travel to the Czech Republic for the second leg next Thursday and have to find the net at least twice and keeping their hosts scoreless.
It was an exciting night in Tallaght Stadium, and Bradley is confident that his side can cause problems for Mladá Boleslav with their dangerous attacking options.
"It was obviously a roller-coaster of emotions up and down the touchline all night, but like I said, it was a real high quality game. Two teams that played some good football and both teams on the attack looked dangerous."
