Even Chris Armstrong scored 48 league goals in 141 league appearances for the club.
Solanke has a total with all his clubs combined in the Premier League of 38 goals in 163 appearances.
I've no idea why Liverpool bought him as he didn't play that much or score much - and he didn't do much initially at Bournemouth, but seemed to get himself back on track when they were in Championship.
Probably fairer to look at his last 2 seasons (last one at Bournemouth and his season at Spurs where he got just over 20 goal involvements. Its not stunning but its not bad either and there were not better alternatives available at time. He is a hard worker though and presses like a demon which opens up opportunities for other Spurs players close to opposition goal so he's got that going for him.
Woolwich went for Gyokeres whose stats were far worse at a higher price, and same for Isak at Liverpool despite a fee of circa 100m. We have definitely done better than either Woolwich or Liverpool with Solanke than their choices.
