Arsenal manager Arsene Wenger deserves his reputation as a coach he's harnessed top young talents and given them the chance to shine at the highest level, but his record when spending big on proven players is patchy to say the least.
Wenger is definitely under pressure once again this season and a large part of the season for the frustration of many Arsenal fans lies in the way he's handled expensive signings, just look at the case of German forward Lukas Podolski.
The 120-cap international came on to rescue Arsenal against Anderlecht in the Champions League with a clinical late winner from close range, but to say he's had a peripheral role at the Emirates so far this season would be putting it mildly.
Podolski has started just one game in the League Cup since rejoining his Arsenal team-mates as a World Cup winner in August, with three sparing substitute appearances in the Premier League amounting to just 54 minutes of action.
Has £10m deal, £100,000-a-week deal been value for Wenger?
Wenger signed Podolski in 2012 in a £10 million deal primarily to help ease the impending woe over Robin van Persie's exit to Manchester United, but quickly had to accept the clinical finisher's game isn't suited to a central strike role.
Podolski is at his most potent on the left-hand side, when given the freedom arriving meet crosses from an advanced position.
Despite being a huge Arsenal fan favourite and one of the most ruthless finishers at Wenger's disposal he's rarely been given a regular run in the starting XI across two seasons or so in North London, with a very different option in Santi Cazorla often preferred.
Can you guess which four players join Podolski in this hall of shame?
You have to feel that Wenger's failed to get the very maximum from Podolski, a player who was particularly driven to prove he belongs at a top club after failing to make the grade at Bayern Munich.
Wenger also deserves criticism for other players Arsenal paid more than Podolski for, stars who the Gunners needed desperately to shine but clearly lost confidence under the experienced Frenchman and ultimately flattered to deceive.
Even Arsenal fans who still believe Wenger can lead the team to glory before he calls it a day have to admit he's got it wrong with four player we've decide to profile in a revealing countdown which shows what might have been the Gunners.
