The former Bolton manager also admitted that his side will not be scoring bags of goals between now and the end of the season.
He said, “Common sense says that if you’re in possession of the ball then use your abilities your intelligence to keep the ball off a side who is desperate to win the game.
“They may then give you the opportunity to win it which they may have done just before the end with Gylfi’s chance but obviously it was a very good challenge.
“But that lack of ability to keep the ball moving and keep the ball in their half to try and create the opportunity to score, we felt let down in that department.
“They hit us on a quick counter-attack and we didn’t recover from that and a deflected shot goes in.
“You can say that’s unlucky but we shouldn’t have let them get in that position in the first place.
“We look at both goals and they both could have been avoided, the first one particularly.
“I thought we’d get at least a draw when we scored because we were looking a much better attacking force but losing two goals is a big disappointment.
‘It’s a disappointing day, not just the result but in terms of creating and getting opportunities to score.
“The bottom line is that we have to be a very good defensive side because our squad is not blessed with goals and we must remember that in our squad at the moment there isn’t two very good goal scorers.
“We’re always going to have to be defensively very sound between now and the end of the season because we’re not going to be a free scoring side.”
