Ryan Nelsen believes West Ham have issued a statement of intent by tying Winston Reid to a new deal.
Tottenham are keen for striker Shaquile Coulthirst to continue his development out on loan after his spell at Southend.
The defender, who joined from Bradford last summer, put pen to paper on a new two-year deal on Friday.
His new contract came amid speculation linking McCall with the Sheffield United job, although the manager has stressed he has no great desire to quit Fir Park.
Ramsden would be reluctant to witness the departure of a boss he has had a happy history of working under.
He said: "Personally, it would be a huge loss because this is the second time I've played under the manager.
"He signed me for Bradford and then brought me up here. From my point of view, it would be a massive loss.
"I'm sure for the club and the fans it would be exactly the same, after what he has done over the last few seasons. We'll all be hoping that he stays."
Motherwell have already secured second place in the Clydesdale Bank Premier League but head into the last game of the season tomorrow against a St Johnstone side who are still vying for a European spot.
With Inverness also still in the race for the final Europa League berth, Ramsden insists Motherwell will show respect for the battle for third place by giving their all as usual at McDiarmid Park.
He said: "After the season we have had, we will go into the game with a lot of confidence.
"It is nice to have the pressure off and knowing that we don't have to win to seal the second spot.
"We know they are going to be well up for it because they need to win to get that third place. We are going to have to be on our game and I'm sure we will be.
"Sometimes you get to the last game of the season and neither side are playing for anything and it can be a bit of a testimonial type feeling.
"We've still got a job to do and we want to go out on a high and finish the season with another three points if possible.
"We know we've got to do justice to Inverness as well and field a strong team and do as well as possible."
The trip to Perth will be the final Motherwell game for some players, with goalkeeper Darren Randolph and Nicky Law quitting the Steelmen, while others are still mulling over their futures.
Ramsden said: "It's a shame but that's football. Some of the lads have had incredible seasons and there is going to be a lot of interest in them.
"That's part and parcel of the game. Everybody wishes them well if they do move on."
