Prior to West Brom's 1-0 defeat of Newcastle last week, boss Tony Pulis said Saido Berahino was 'lucky to even be on the bench'. What a stark contrast from last season, when the English starlet was in fine form and scoring at will for the Baggies.
Clearly, Berahino doesn't yet have the right attitude or mindset to succeed in the Premier League - here are five other players whose attitudes have hindered their progress.
Let's get the obvious one out of the way. Robinho was Manchester City's first big buy under new billionaire owners Sheikh Mansour and touted as the next big thing upon his arrival from Real Madrid.

The Brazilian scored 14 league goals in his first campaign at the Etihad, suggesting his £32.5 million fee was money well spent.
That was until he picked up an injury that left him out for three months during his second season with the Citizens. Upon his return, Robinho struggled to get back into the team and when he did play, he didn't playing well.
As a result, he demanded that he was sold and City duly accepted. Now 31, Robinho plies his trade in the Chinese Superleague for Guangzhou Evergrande after failing to re-establish himself.
The talent is there; the physicality is there - it's just a shame the attitude isn't. Jose Mourinho, whilst manager at Inter Milan, claimed the mercurial Italian was uncoachable yet he was bought by City.
While he was quite the player during his first two seasons in Manchester, his off-field antics led to several high-profile fallouts with then-boss Roberto Mancini.
Eventually, his performances on the pitch - such as a red card against Arsenal - suffered and he fell down the pecking order.
In his third season, Balotelli challenged a fine that he received for poor conduct in the previous campaign and missed a total of eleven games through suspension.
Despite all this, Brendan Rodgers thought it were possible to coax the best out of him at Liverpool. He scored a single league goal all season and returned to AC Milan, where he has enjoyed a mixed spell.
His goalscoring exploits when he arrived at Sunderland were nothing short of explosive, finding the back of the net on his debut, his first start and his first league start.
Gyan finished his maiden season in the Premier League with ten league goals and received the number three shirt - the same as he wore for Ghana.
There was only one thing on the striker's mind, though - money. The next season, the Ghanaian secured a move to Al-Ain of the UAE League, reportedly worth quadruple his salary at the Black Cats.
Naturally, the UAE League received little recognition and Gyan's name is largely forgotten amongst football fans.
HATEM BEN ARFA
A slightly controversial choice, but considering the Frenchman was supposed to be one of France's greatest talents, 13 league goals in 76 games for Newcastle is a poor return.
Often accused for playing with a selfish attitude, Ben Arfa was eventually shipped to Hull City on loan, where he failed to score a single goal.
Midway through his loan move, the France international disappeared from England, with manager Steve Bruce unaware of his whereabouts. He later revealed his career at Hull was over and, upon his return to Newcastle, failed to re-establish himself.
He has since moved to Nice and showcased his undeniable ability, dribbling past players at will and scoring some quite spectacular goals.
Southampton broke their record transfer fee to sign the Roma striker and with good reason - his exploits for the Italian club resulted in 27 league goals in 55 appearances.
But he failed to make a similar impact at St Marys, bar an excellent goal against Chelsea. It was more due to his off-field antics as opposed to anything else, the Italian receiving a fine for violent conduct and then arguing with teammate Jose Fonte.
After 13 league games, Southampton announced the termination of his contract.
Talent is evident in a lot of professional footballers; attitude and determination are not. It is only with the right combination that a player can succeed in the rigours of world football.
