Grenada took 4 points in their last 2 matches, but still is 19th placed and I really doubt they will be able to avoid the relegation this season. Grenada is the team with the weakest attacking line, scoring only 4 goals this season. At home they has scored only 2 goals in 6 matches, but also playing ultra defensive , conceding only 3. Grenada made 3 draws in their last 4 home matches.
Mallorca is one of the weakest away teams in Spain. They are 0-2-3 on the road with goal diff. 3:11, having scoring problems. They are on bad run of 6 games without win, making 4 draws. They got 2 draws in their last 3 away matches, losing from Barcelona in last visit with 5:0.
I expect close game, maybe without goals, but draw will cover eventual 1:1 result
