Improve to what position? 7th. What good does that do us. We still won't have Europe and our wage bill won't have increased by much.
We are still behind Chelsea, City, Utd, Arseanal, Spurs, Liverpool and probably also Leicester and maybe even West Ham.
If we are going to do it then we need to buy better players. Even if it means we buy over a few years. Can you imagine where we would be if we followed up the season we bought Lukaku, Stones and Deulofeu with two more seasons were we bought 3 top class young players.
Our problem with Martinez was after Rom we didn't have the money to buy another Rom for another 3 years.
