So far it seems to be working just fine.
Michael Higdon and Henrik Ojamaa plundered 31 goals between them and, although the Liverpudlian claimed the lion's share, he would not have done so without Ojamaa, whose 16 assists were a league best. The pair left in the summer - Higdon for NEC Nijmegen in the Netherlands, Ojamaa for Legia Warsaw - to be replaced by a duo of identical nationalities and similar efficacy.
Norwich-born John Sutton has returned to Fir Park from an unhappy spell at Hearts and continues to show why, with the right service, he is one of the deadliest strikers in Scottish football. His two goals against Ross County on Saturday turned the game in Motherwell's favour, the first a header from a corner, the second a fierce shot into the top corner. Having also come close with a free kick that was deflected wide, he is clearly a player enjoying a rich vein of form. Already he has five goals to his name this season.
Sutton is not doing it all alone, however. Playing alongside him is Henri Anier, another Estonian, who pitched up at Motherwell at the end of July on a six-month loan spell. The Viking Stavanger forward has already scored four times this season - matching Ojamaa's total for last year - and was unfortunate not to add to that tally against County. Even without scoring, Anier still made a contribution, sliding a perfect pass through to Sutton for his and Motherwell's second.
It is still early days but already the signs are bright that this Anglo- Estonian axis will deliver the same results as the one that preceded it. "I's a partnership that's building week on week," said Keith Lasley, the captain of Motherwell. "Even in training you can see them learning from each other's games. Big Sutty has been outstanding this season, he's probably been our best player over the last few weeks. He's a real target for us and a lot of our play is going through him. Henri's just working off that. Sutty's second goal on Saturday was the perfect example of that."
Motherwell had to rally from a goal down before cantering to the three points on the back of a strong second-half performance that also brought about a third goal from substitute Bob McHugh. They appear to be building up a head of steam, this win taking them up to third place in the table behind Inverness Caledonian Thistle and Celtic, whom they face this weekend.
This is McCall's third full season as manager and it seems that, once again, he has recovered from the loss of several key players to put together a squad capable of challenging at the top end of the league. As well as Sutton and Anier, Lionel Ashworth - another recent loan signing - impressed in the second half, while Stephen McManus was again solid at the back. Paul Lawson and Iain Vigurs, stalwarts for County last year, had to settle for a seat on the bench against their former club, highlighting the options McCall now has at his disposal.
Lasley admits he began to wonder just how Motherwell might fare when Higdon, Ojamaa, Tom Hateley, Chris Humphrey, Nicky Law and Darren Randolph all moved on, but so far it looks as if McCall and his scouting team have again come up trumps. "There's always a little bit of you that thinks every summer 'can we do it again?' - especially given the relative success we've had in previous seasons," said Lasley. "We're not as big as the Edinburgh clubs, Aberdeen or Dundee United and you expect them to be up there challenging. But we've done well consistently and hopefully we can continue to do that. The manager's recruitment has been a massive part of that."
County are still waiting for their season to catch fire. A fifth-place finish last year has created an expectation that Derek Adams' side will again feature in the top half of the table, something they have so far failed to achieve. Against Motherwell they showed promise in glimpses, and led at half-time through Melvin de Leeuw's deflected shot, but were soundly beaten by the end.
Given how strongly they played in the second half of last term, however, they are not getting too down about it. "Somebody told me the other day we're only a point behind where we were last season," said defender Scott Boyd. "So we know ourselves that if you can win a couple of games you'll move up that league."
