Declan Bonner admits that his side have had plenty to work on ahead of Sunday’s NFL clash with Monaghan in Fr Tierney Park.

The Donegal boss again watched his side surrender a position of strength in Croke Park last weekend as reigning All-Ireland champions Dublin came from behind to pip Tir Chonaill down the home straight.

Mayo and Galway have also staged late revivals against Donegal in this league season and it remains very much a concern ahead of the Farney men’s visits to Ballyshannon.

Donegal were better defensively on Jones Road last Saturday night than they were in previous matches, but they still gave away a poor three-pointer and that has been a recurring theme.

“The goals we are conceding, we are disappointed with,” said Bonner.

“Again we are defending well for long, long spells, but Dublin’s goal again came from an error.

“We have created a lot of goal chances in the four games that we have played to date, and we’re disappointed that we didn’t add a second goal (against Dublin).”

The big positive from the defeat to Dessie Farrell’s side was that Patrick McBrearty returned to the fold and he looked sharp.

“Yeah it was good to get Patrick back on the field and that was a big plus for us. He will go from strength to strength now.”

Bonner’s main concern centres on Jamie Brennan who hobbled off late on at Croke Park.
