Firstly, as far as I know the club aren't looking to get rid of Maxi. He's a very useful player and with the Marveaux deal falling through, we could do with as many options in the wide areas as possible.
As for Jovanovic; a much to do about nothing story was started over his wages. He's on ~£60k per week and reportedly got around £3m signing on fee (which all players get whether bosmans or not). For 1 reason or another it was agreed that the £3m would be paid over the first year of his deal rather than up, resulting in the £120k per week headline figure. It's recently being reported that he's close to leaving and according to some reports, with no pay off from Liverpool.
WHy on earth wouldn't you get rid of Maxi, 1 assist and, but for 2 games against two teams on their worst performances of the season by a massive massive margin, 4 goals. He scored 3, and then 7 of his ten against brum, Newcastle, Fulham in consecutive games at the end of the season. Most were tap ins, put on a plate for him and against one team that had all but given up(and was rubbish) and one team where their best CB had just about the worst game I've seen any defender have in the premier league.
Without those 2 games he was on course for another epic failure of a season. After a pretty awful first season, an awful 90% of this season, 2 games will change your opinion on a guy on high wages who offers incredibly little to the team? Someone on 1/3rd his wages is likely to be as useful, yet theres potential for a cheaper/younger player to improve, Maxi has been in a fast decline for 3 seasons, 2 games really doesn't change that.
EDIT:- On checking, only his one goal at Bolton and one of his goals at Fulham made any difference to the result, the other games he scored in Liverpool were winning or would have won without his goals, 3-0, 5-0, etc, etc, like Malouda he only scores when the team is having an easy game, of the 7 goals across the 3 games at the end of the season, only a single goal had an effect on the points. Malouda and Maxi aren't guys who change games, who win games, they just get some tap ins when the team is smashing the other side to pieces.
As for Jovanovic, I said I'm not sure, just saying whats been reported, though I wouldn't take for gospel what you're saying about signing on bonus, its unclear though if you meant every player gets a bonus, or if every player gets 3mil, the later is either horrific business, or not happening, the former, of course. Most other teams end up giving hugely higher signing on bonuses for free transfers, and 3 mil would be, afaik, massively massively above the average signing on bonus even for the majority of top players.
I generally try to keep an open mind to all sources of info, where several have said 120k a year, others have said 60k, and others have said high but not for his whole contract, but whenever its Liverpool you always automatically accept the rumour the works out best for Liverpool, always.
Someone pointed out that every single time Liverpool make a signing, you always make a post how its not really that much, its way lower, but may get X high. Its perfectly possible Jovanovic is on 60k, equally possible he's on a truly stupid wage as he was a free transfer. Frankly 60k a week for a free transfer who was expected to be first team, an international, seems low.
