Quite a pricey option but Benteke is a god in that role, banging them in for my Tottenham team! Another option would be Andreas Cornelius I think his name is, goes very cheap if he hasn't already been picked up by someone. Possibly Nicklas Helenius also.
1 other good TM i can think of is Fabrice Olinga (16y, Malaga). This guy is the definition of the TM in my CFR Cluj save. Thanks to him i won the EL and beat Barcelona 2 times in the UCL group, and he rocks in the league. He has a goals scored/games played ratio of over 1. Of course, he is too young at the start of the game.
