Dewi Morris says Saracens' relentless hard work saw them edge Gloucester 28-23 at Vicarage Road on Sunday afternoon.
A Richard Wigglesworth try, plus a conversion and seven penalties from Charlie Hodgson, secured the victory for Sarries and moved them up to second place in the Aviva Premiership standings.
"Saracens are good at chasing everything and working for one another and when Gloucester were a bit lethargic and didn't chase, they pounced," said the Rugby Club regular.
"You don't have to love Saracens but you have to respect the fact that they never give in, they grind teams down, get into position and nine times out of 10 kick for goal."
Morris' fellow analyst Dean Ryan says Gloucester's hopes of capturing the points were shattered by sin-binnings for Sione Kalamafoni and try scorer Dan Murphy - and some poor kicking by fly-half Jimmy Cowan.
"Gloucester will be kicking themselves; they were more muscular around the driving, more muscular around the scrum and everything was under control," said the former England star.
"They had two yellow cards to contend with and you can't afford to have them when you know the game is going to be that tight; the Kalamafoni one hurt them, in particular, because they were clearly trying to slow Saracens' ball down.
"Plus, Jimmy Cowan, who has been a great influence on this Gloucester team but has been repeatedly let down by his box kicking, should have kicked into touch but he didn't - and Saracens took their opportunity."
Ryan added: "Saracens don't like being behind because they don't have the bubbles and fizz to chase a game, but when they are in front they are under control and they have laid down a big marker by beating Glocuester."
