21 goals, our highest return from a striker in years. I'm not saying he should be first choice but I wouldn't be rushing to get him out the door.
21 goals on the face of it may seem like a decent return but it's taken him 51 games to get there, or a goal every 2.4 games. Morelos for contrast averaged 1 in 2.1 over his Rangers career and was a far superior forward at his best.
If you look at their stats for the league campaigns in the last two seasons, there's an argument that he's not even as effective as Morelos at his worst.
Dessers 15 league goals beats Morelos 11 of last season but it took him 641 more minutes to get there. Morelos managed a goal every 135 minutes. Dessers is averaging a goal in the league every 142 minutes.
If you factor in Morelos 6 assists to Dessers 3, in terms of goal contributions in the league, Morelos managed 17 and Dessers has managed 18. Dessers has played 2133 minutes to morelos 1492, over 7 games of a difference. Morelos goal contribution rate was 1 every 87 minutes. Dessers is 1 every 118 minutes.
Colak managed 13 goals in 1392 minutes or 1 in 107 minutes. His 3 assists put him at a goal contribution rate of 1 every 87 minutes.
Dessers stats are padded by the fact he's been the only option we've had for so long, he's played so many minutes of each game. He's statistically the poorest striker we've had out of the three in the last two seasons.
It's not all about goals and assists if you are the type of striker that can hold the ball up, bring people into play, occupy defences or press. Dessers can do none of these things.
I'd play Morelos or Colak ahead of him tomorrow if it was possible, the guy is just not good enough.
