"We have had to cut training twice this week as we only had four fit players available. I know there will be some players definitely missing for Inverness but that will create chances for some of the other players," McCall said. "You just have to go with what you've got, though, and that's what we will be doing. We don't know what we will travel with and will have to assess the squad before we leave on Saturday.
"When you have a small squad you have to wrap players in cotton wool, but whatever the side that goes out there on Sunday, they will be going out looking to win. "Some of the boys have come back to training today (Friday). It will be a competitive side we put it out, but some of the guys won't make it and there will be some who play not fully fit." McCall's team have recorded just one win in their last seven league matches, but despite their dip in form the boss is remaining positive.
Motherwell could not build on an impressive victory at St Johnstone two weeks ago as they lost at home to Dundee United and were then held to a 1-1 draw by Dundee. "If I look back on the last few games, we are playing as well as we were at this stage last season," McCall said. "We are just struggling to find that elusive goal when we are on top. When we have been dominating games we just haven't been taking our chances - it's a thin line between success and failure.
"I would be more worried if we weren't playing how we are playing. We may not be getting that little rub of the green that we did last season, but we're still a good side and are playing some decent stuff." Motherwell travel to Inverness on Sunday aiming to become the first side to inflict defeat on Terry Butcher's men for 10 games. Inverness' last loss came against Motherwell at Fir Park over two months ago.
"Inverness have the same case as us in the sense they have lost late goals in their last two home games," McCall added. "They are a good unit with an excellent spirit about them and good quality players. "Probably the only time last season we went somewhere and came away with something when it was undeserved was at Inverness. I would accept that again if it meant getting back to getting all three points."
