Leaving the manager in a heap with a shuddering challenge is not normally the best way to endear yourself to your new employers. Manchester City new boy Stefan Savic clearly didn't read the small print in his contract!
The £7million arrival from Partizan Belgrade wasted no time in getting stuck in to City's pre-season training sessions, and clattered Roberto Mancini with one no-nonsense challenge prior to Monday's friendly with Vancouver Whitecaps during their tour of the USA.
Fortunately, Mancini took his battering in good part as the players on the training ground, initially, held their breath before roaring with laughter as the boss emerged smiling. No doubt there was a sigh of relief from the new boy.
Savic's abrasive, all-action approach to training is something City will have to get used to and keeper Joe Hart, for one, has welcomed his new colleague with open arms. "It was awesome," he beamed with a wry smile. "I was watching it. Brilliant. The gaffer was training and Stefan properly did him.
"I think that's a statement of intent. The gaffer took it well, I think he loves all that," he continued. "If the boss wants to get involved in training I think he should realise he will get the treatment off the players.
"Everyone had a laugh about it, I was roaring with laughter. I liked it. You train as you want to play."
Hart went on to say that the competitive nature of the Blues' sessions had generally been an eye opener to all of the club's newest recruits.
"Gael Clichy didn't know what had hit him with people flying in," explained the 23-year-old. "There was no malice in it but if the ball is there, you want it.
"We're all men and sometimes there's a bit of bad blood, but obviously everyone respects each other. We're a football team, not a bunch of idiots who just go around fighting each other, and we just want to keep proving that we're winners."
