Motherwell could qualify for Europe on Saturday, but Stevie Hammell still wants more than a third place finish this season.
’Well will be in the draw for next season’s Europa League if they beat Dundee United at Tannadice, while Inverness fail to take three points off Celtic the next day.
Hammell said: “It will the biggest game of the season, at least until the next one.
“United will be keen to close the gap on us, while we are looking to keep them away, while at the same time trying to catch Aberdeen.
“There will still be some twists and turns to come between now and the end of the season.”
’Well have taken just a point from United this season in a 2-2 draw at Tannadice in September, but were beaten 4-0 and 3-1 in their previous two meetings.
However, Hammell doesn’t think what came before will have much bearing on Saturday.
He said: “For the 4-0 defeat we had numerous injuries and to be honest I hardly even remember the other loss.
“Both teams are pretty even, they have plenty of attacking threat that we need to be aware of, but we will work hard on our game and do what we need to in order to stop them playing.
“Third place wouldn’t be the worst result at the end of the season, but we need to keep an eye on Aberdeen and keep pushing them in the race for second.
“It’s a cliché, but we take one game at a time and as each one passes we see where we are and hope the other results have gone for us.
“But, for now we concentrate on Saturday, it’s one of our biggest games for a long time and we’ll be ready for it.”
