The Television presenter took to social media after Rangers drew 2-2 at Hearts.
Richard Keys was unimpressed on Twitter after Rangers blew a two-goal lead at Hearts on Saturday afternoon.
And that lead lasted for the majority of the match - until Hearts hit back in the last 10 minutes.
Indeed, Genero Zeefuik came on for the home side and netted a quickfire double to steal a point off Rangers.
The result means McCall's side finish the season third in the Scottish Championship and television presenter Keys feels it'll be a 'big ask' for Rangers to go up based on their play-off fixtures.
Rangers will now play QoS - who've beaten them H & A this season - then Hibs x 2 - then probably M'well to get up. Big ask.....— Richard Keys (@richardajkeys) May 2, 2015
Rangers have suffered a season full of on and off-field turmoil, with Ally McCoist, Kenny McDowall and McCall all being in charge at Ibrox at different stages of the campaign.
Promotion is still on the agenda, of course, for the Gers - but, as Keys suggests, it certainly won't be easy from here.
Can Rangers still go up - or will it be another season in the Scottish Championship for the Glasgow outfit?
