The Internet is full of reactions to Celtic's stunning 2-1 victory over Barcelona on Wednesday.
The best of the lot might have come from the Spanish press. The Daily Telegraph provides an excellent roundup here, with the lead image sporting the headline, "The Great Wall."
Mundo Deportivo referred to Celtic as "Bravehearts," and Marca reported the following:
Good defensive tactics, an amazing performance by Fraser Forster in goal, a partisan crowd and a pinch of good luck. With these ingredients, Celtic cooked up a night on which Barcelona were unable to offer their best. There is perhaps no greater home pitch advantage in all of football than a Celtic match at Parkhead... as Barcelona learned the hard way.
AC Milan, Manchester City and Chelsea are possible destinations for manager Pep Guardiola next season, according to agent Jose Maria Orobitg (via ESPN FC).
Guardiola, 41, managed Barcelona to 14 trophies in four years before stepping down at the end of last season. He is currently not managing a team but is thought to favor a return to the touchline next season.
"Pep is listening to offers and evaluating them," Orobitg said. "But Guardiola will not coach this year. We'll talk about it in June."
London's Olympic Stadium will not be ready for use as a football ground until 2016, according to Dennis Hone, the man in charge of the process (via The Independent).
Four clubs have presented bids to move into the stadium. West Ham's bid is thought to be the favorite.
The renovated stadium will hold about 60,000 people. The conversion is expected to cost £200 million.
Manchester City manager Roberto Mancini will reportedly ask director of football Txiki Begiristain to sign Italian midfielder Daniele De Rossi in January (via Daily Mail).
De Rossi, 29, has reportedly told friends he wants to leave Roma, his only professional club. The Mail reports that Roma would ask at least £20 million for De Rossi, who would be paid about £100,000 per week.
Arsenal midfielder Jack Wilshere wants the club to give winger Theo Walcott a new contract (via The Sun).
Walcott, 23, is in the final year of his contract, and negotiations have not yet produced a new deal. He joined the club from Southampton as a teenager in 2006.
Meanwhile, the Daily Mirror reports that Arsenal are considering a bid for Queens Park Rangers midfielder Adel Taarabt.
