Montoya seems to be on the outs with Barca. It could force their hand into a favourable transfer for us. He wants to leave and it seems they can't be bothered if he leaves. 20M is outrageous. I would pay 10M, maybe 12M over 4 years. Nothing more.
Montoya has some positives. He can play RB or LB. He has very good energy like Lichtsteiner. Very good off ball movement. Eager to make attacking runs. He's lighter than Lichtsteiner in defence (it will be hard to find a RB as good as Lichtsteiner defensively). I would say he's better than Lichtsteiner offensively but he's not exactly an attacking RB.
Better ball control, quicker decisions, quicker feet, tighter dribbling, better crossing (slightly). Grew up in La Masia, you know that type of player. But he's not an offensive RB to me. He's not like Maicon who can shoot from anywhere or can run the whole flank even at his current age and put a laser cross in. He's a stable option offensively.
He is a good tackler from what I've seen but lacks great size and strength for me. He's more of a modern RB who can play the ball but is not like Lichtsteiner who can be a prick, crunch people, man mark flawlessly on set pieces, etc.
I think our board likes his mentality though. He's a soldier on the field, something we always valued. Keeps his head down, moves the ball, gives an honest effort every match. He will not cause problems and fit with the team.
He has been benched at Barca for his whole tenure there. He's quite possibly the best RB option on the team right now but never plays so it's natural for him to want to leave. I don't think it's an indictment on his character. His treatment at Barca has not been great.
