If we intend to play 4-4-2 at any point then yes. If we're sticking to 4-5-1>4-3-3 then we need cover for the target man and to address the shortfall in attacking wingers (inside forwards) first. With Baldock injury prone I would concede we need another support striker/amc with pace though...
Attacking wingers who rather than run to the byline and get a cross in, cut inside and run towards goal and attempt to score or lay-off to a team-mate in a goalscoring position. The best teams invert them (lefty on the right wing, righty on the left). Knockaert is a textbook inside forward...
This whole obsession with strikers is getting on my pip. People are so backward thinking and don't realise the game has moved since the 80s and the halcyon days of 4-4-2. Take a look at the really successful teams...All the top the 4 in the prem last year, Barcelona and Real Madrid among others...
