For this February super match day thing I went in on Matz Sels. Here is what's happened so far after 2 weeks of holding him.
I was apprehensive so only bought 140 of him.
Bought at 22p per share. For £30.80 total.
Earned 10,500 super match day points for the purchase: 42p.
Clean sheet Vs Toulouse: £1.40
Clean sheet Vs Reims: £1.40
3 games so far in Feb with PB scores of 66, 118 and 104. Total of 288 multiplied by 140 shares is 40,320: £1.61
No cap app, price still 22p.
Total earned so far: £4.83 = 15.6% ROI in 2 weeks.
Still has 3 matches this month eligible for IPD and Super match day vs Lyon, Amiens and Montpellier.
I expect my ROI will be over 20% by month end.
So are there value on goalkeepers? Yes...if you buy them at the right time and if you can get them cheap enough. IMO there is not much point buying a GK priced more than about 30-35p. If you can get a starter for less than 25p, you can easily make 10%+
