Bruno Lage was a decent manager but it was obvious that he was gonna sacked after poor performance coming into the new season but squad will need a good strategy to put up a good fight against Chelsea which I doubt from the interim manager whoever they have given the command to. Costa signing is more like a backup as they already have good strikers but prone to injuries. With both Jimenez and Sasa injured, I think they should start Costa and if they do then I think there is a slight possibility of Wolves surprising the Blues.
