"No-one likes to play open football more than me," Redknapp said of the weekend's game. "But if you start slugging it out with the likes of Manchester United, you'll get outslugged"
With this in mind, Redknapp is likely to strengthen his flanks to fight the threat of United wingers Ryan Giggs and Cristiano Ronaldo as Portsmouth aim to stretch their unbeaten run to five games.
Redknapp may have to rethink his strategy, however - the 19 year old Ronaldo may be rested for the Portsmouth game. Considering the damage he did to relegation rivals Leicester City on Tuesday, that can't be a bad thing.
