Think he would be better off buying for those upfront 3. Even move Suarez left and bring in a new central player.
As much as Gerrard is a great finisher, I don't know if his legs will last long with that running up front. He may get more years as a playmaker, if he can resist passing to the oppo and do it well.
Gerrard doesn't have the same burst of pace he once had but there's still enough in the tank in my opinion. You saw towards the end of today's game when he burst past Chelsea's midfield and slipped Sterling through. We certainly need to bring a couple of attacking in but given our current options, when Lucas is fit, I'd certainly give Gerrard a run further forward.
