With spending this summer set to be at a similar level to that of 2011, significant investment in playing talent, both in terms of player transfer fees as well as wages, looks set to continue in both the January and summer transfer windows.”Once again, Chelsea look set to lead the way this summer having spent more than £75m on Eden Hazard (£32m), Oscar (£25m), Victor Moses (£9m) and Cesar Azpilicueta (£7m). Manager Roberto Di Matteo remains in the market for a striker.But none of Arsenal (Santi Carzola £16m, Olivier Giroud £10m, Lukas Podolski £11m), Manchester City (Jack Rodwell £15m), Manchester United (Robin Van Persie £24m and Shinji Kagawa £12m), or Liverpool (Fabio Borini £11m, Joe Allen £15m, Oussama Assaidi £3m) have come close to matching the £50m plus each club spent last summer.
