If Barcelona had any sense, they would make Dani Alves an acceptable offer to stay at the club right now.
Because once again Martin Montoya has shown everyone exactly why he is not the right man to replace him.
The youngster, try as he might, just does not fit the Barcelona template and what successive Barca managers have been looking for from their wing backs.
Given the job against Paris Saint-Germain because of Alves' suspension, Montoya was gifted the opportunity once again to prove his worth to the club and to deliver a high-quality performance that left no one in any doubt that we were looking at Barca's right-back of the future.
What we saw, again, was a young man lacking in confidence and seemingly overawed by the occasion.
How else do you explain his reticence to get forward and provide a supplementary attacking presence down the right channel, a la Alves?
Fortunately, PSG weren't at the races and the fact that Lionel Messi had to drop much deeper than normal and plough his own furrow largely went unnoticed.
The Argentine was still decisive which neatly overlooks the shortcomings of a player who doesn't appear to have the word attack in his vocabulary.
Make or break
At 23 years of age, this really was the make or break season for Montoya.
He was close to leaving at the beginning of the campaign because of lack of opportunities, and again during the winter window, but perhaps because of an impending Alves exit, he has been kept onside at the club.
That said, he's played nothing like the amount of games that both he and his agent had suggested he needed to play in order to sign another contract with the club.
Barca appear to have realised their error in playing a game of brinkmanship with Alves, but now it's the Brazilian's turn to play hardball.
If, as expected, Alves decides on pastures new, then Montoya (if he stays) and Douglas are their only viable options with the possible exception of Adriano Correia, playing out of position.
For a club of Barcelona's standing, it's an absolutely ridiculous situation to find themselves in.
Perhaps they are waiting for Montoya to blossom, but it just isn't in his nature to be the player that Barca need him to be.
He is not, and never will be a marauding right-back slinging in cross after cross from first to last minute. That's not his game and in fairness to the player, it never was.
So, the Catalans need to change their style to accommodate him or swallow their pride and secure Alves on one final contract.
Time is running out...
