After suffering yet more disappointment in the Premier League over the course of the weekend, Arsenal return to the Champions League this week, though that is unlikely to be much better for them at all.

Already trailing Bayern Munich 5-1 following a first leg capitulation at the Allianz Arena, the Gunners are unlikely to progress to the quarter-finals for the first time in seven years, even if they manage to beat Carlo Ancelotti's side.

Perhaps indicative of the problems affecting those in north London right now is the sheer difference in class between themselves and the Bundesliga giants. In truth, there probably isn't a huge amount splitting the two financially, considering the riches on offer in the Premier League these days, but the attitude of the two clubs couldn't be further apart.

Both would be considered powerhouses of European football, though you'd get the feeling that any top player worth his salt would opt to move to Munich over Arsenal, with Bayern always battling for honours both home and abroad.

So, to further explain that point, here'a look at THREE Bayern stars Arsenal could only dream of signing.

Robert Lewandowski

One of the major problems at the club over the last few years has been the lack of an elite striker to properly spearhead the side, with Olivier Giroud continually dividing opinion at the club. Ironically enough, perhaps the ideal marksman to finish off this Gunners side would be Bayern star Robert Lewandowski.

Technically gifted and a wonderfully lethal finisher, the Pole is among the finest in Europe, though surely he wouldn't consider the idea of swapping league titles for a top four battle.

Xabi Alonso

Granted, the former Liverpool and Real Madrid superstar is retiring at the end of the campaign, so Arsenal couldn't sign him anyway, but he would have been the ideal man at the Emirates Stadium even back in 2014, when he moved to Germany.

It's more indicative of the mentalities within the two clubs. Arsenal would never have signed a man in his mid-30s from Real Madrid, though the nature of Alonso's masterful game means age really doesn't play too big a part in his level of performance. Instead, Bayern moved for him and he brought his winning mentality as they romped to yet more success.

Thomas Muller

Interestingly enough, Thomas Muller hasn't really been a regular starter in Munich of late following a run of relatively poor form. However, it seems the idea of playing back-up at a powerhouse of continental football rather than starting at a backwater such as Arsenal is preferable to the cream of European football these days.

Muller is a natural born winner and has enjoyed success both domestically and internationally. Considering the problems Arsenal are facing with Alexis Sanchez these days, another man to have that sort of mentality, Muller would find life at Arsenal frustrating.
