While Donegal manager Jim McGuinness was "delighted to get the points on the board" following Sunday's Division One win over Mayo, he feels "there's a lot of tidying up to be done from the second half".
The eight-point win maintained the Ulster champions' perfect start to the league as they now sit clear at the top of Division One.
Conor O'Donnell's goal midway through the second half put Donegal in a commanding position and while there was much to be happy with, McGuinness felt there is plenty to work on for the rest of the campaign.
"We controlled the game well (in the first half), the build-up (play) was good and we managed to get out because we were playing against a really aggressive Mayo team that like to get after the high press," McGuinness told BBC Sport NI.
"We got sloppy in the second half with a couple of hand-passes that went to feet and stuff like that, fellas shooting balls that dropped short and both kick-outs dropped again, so there is a good bit to work on, but it's the time of the year to do it. At the same time, we'd be happy with their application."
Donegal make the trip to face Armagh next week in a repeat of last year's Ulster final and victory there would leave them in a very strong position to qualify for the league final.
However, McGuinness is thinking bigger picture and their Ulster Championship quarter-final against Down in late April he is "hopeful" will take place in Ballybofey should the MacCumhaill Park pitch be available after upgrade work.
McGuinness is also keen to upgrade his squad for the championship and reiterated his plan to use the league to unearth fresh talent.
"Our objectives are the same as at the start of the league," he insists.
"We're trying to develop a wee bit of depth in the squad and give younger players an opportunity like Conor (McCahill) who did very well (against Mayo).
"We're getting ready for championship and conscious of Down's results. They're winning every week as well and had a brilliant campaign at the end of the championship last year, so that's what we're using these games for - to put us in the right spot to be ready for the championship."
