Mateta has only scored 1 goal in his last 6 games and I agree he would benefit from a rest. Nketiah is injured and we don't possess another No 9 with similar physical attributes as Mateta which I believe would be beneficial to us.
a classic example as to how to (miss) use stats to make a point.
On the 7th game he scored a hat-trick so has 4 goals in the last 7 - not too bad.
Agree he needs a rest but his contribution and goal record is ok overall
